11 Most Massive Mines in the World
 
10:20
From the worlds largest gold mine found on the top of a mountain to the largest diamond mine in the world here are the most massive mines in the world! Subscribe to American EYE! 5.. Asbestos Mine, Canada Also known as the Jeffrey Mine, it’s located in Asbestos, Quebec and it was in operation until 2012. It’s a whopping 2 kilometers wide and 370 meters deep! Check out this thing on google maps and you can tell how completely massive this thing is! It’s the by far the largest asbestos mine in the world. For a long period of time, people would use this mineral to put into their walls and keep their homes from catching on fire! But recently there’s been a link with asbestos and a disease called mesothelioma, which is a lung condition. This is a toxic substance that people should avoid, so obviously this large mine went out of business. The lake at the bottom might look like an inviting blue, but you can bet your bottom dollar, it’s highly toxic! The small town that grew with the thriving asbestos industry feels like they’ve kind of lost their identity once the mine was forced to close, but people do still live there. 4. Mcarthur River Uranium Mine In case you were wondering which mine produces the most uranium in the world, that would be of course the Mcarthur River uranium mine in Saskatchewan Canada. This huge deposit was found in 1988 and finally a mining operation took place in 1997, when it began producing what’s known as Yellowcake. It’s not the kind of yellow cake you’d eat with your grandparents. This stuff has a horrific odor and basically what it is, is concentrated uranium powder which can then be used for powering nuclear reactors. We imagine this powdery substance is quite difficult to get ahold of. There aren’t a ton of photos of this place but, it does produce about 13 percent of the global uranium production across the globe. 3. Diavik Diamond Mine In case you thought it was Africa who had all the massive diamond mines, think again! The Diavik Diamond mine, found in the the northwest territories of Canada is one of the largest producers of diamonds in the Northern hemisphere and this place is pretty crazy! They annually produce 7 million carats of diamonds each year and you better believe it’s not easy to get here. The Diavik mine is found north of the arctic circle and it’s definitely cold! This photo here shows the subarctic landscapes that surround the diamond mine. You thought getting to work in the morning was tough for you? Imagine trying to get to work here! Just recently in 2015, this diamond produced what was known as the Diavik Foxfire 187.7 which is one of the largest rough gem quality diamonds ever produced. 2. Siberian Diamond Mine Also known as the Mirny Mine, The USSR began searching for ways to make to make themselves a more economical stable and independent union. In 1955 the Soviets discovered large diamond deposits at this site in the far away lands of Siberia and many people got to work very quickly in order to help bring wealth to the union. After about 20 years of operations, they finally decided that At one point this mine produced 10 million carats of diamonds a year and reaches a max depth of 524 meters or around 1700 feet making it the 2nd largest excavated hole in the world. The mine is so deep, airspace is closed over the hole due to helicopter crashes caused from the downward flow of air. The construction of this in the frigid conditions of Siberia must have been grueling and downright cruel. Sources state that the machinery used at this mine had to be covered at night or it would freeze Are the diamonds worth freezing to death?! It’s unoperational today but Some claim that there’s still a bunch of diamonds in this mine and the whole thing could be worth about 12 Billion dollars. It’s possible that controlling this diamond is mine is crucial to controlling the price of diamonds across the world. Bingham Copper Mine The bingham copper mine located near Salt Lake City Utah is home to the biggest pit in the world and it’s been in operation since 1903. It’s about 2.5 miles wide and if it were a stadium, it would be able to fit an estimated 9.5 million people. It keeps getting bigger and bigger too! Diligent workers can move about 250,000 tons of rock each day and it’s even become a tourist attraction in recent years before a massive landslide took place. Some claim that this was the biggest non volcanic landslide to take place in North American modern history. This photo we see here shows you the aftermath of this massive landslide and Bingham Copper mine and it makes you wonder how safe some of the conditions at these mines truly are. The landslides were so massive, that they actually triggered a few small earthquakes! Experts estimated that 165 tons of earth slide down from the top of the mine all the way to the bottom.

Nickel 1935 US Bureau of Mines; How Nickel Metal is Mined and Refined
 
19:19
more at: http://scitech.quickfound.net "Reel 1, nickel ore is mined, pulverized, and processed to extract nickel sulphide. Reel 2 shows the manufacture of nickel-copper alloy and many of its uses. Famous objects using the alloy include a record-holding speed boat, a zephyr train, an auto racer, and the liner Normandie." Silent, with title cards. Public domain film slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). http://creativecommons.org/licenses/by-sa/3.0/ https://en.wikipedia.org/wiki/Nickel Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel shows a significant chemical activity that can be observed when nickel is powdered to maximize the exposed surface area on which reactions can occur, but larger pieces of the metal are slow to react with air at ambient conditions due to the formation of a protective oxide surface. Even then, nickel is reactive enough with oxygen that native nickel is rarely found on Earth's surface, being mostly confined to the interiors of larger nickel–iron meteorites that were protected from oxidation during their time in space. On Earth, such native nickel is found in combination with iron, a reflection of those elements' origin as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's inner core. The use of nickel (as a natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook its ore for a copper mineral. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), that personified the fact that copper-nickel ores resisted refinement into copper. An economically important source of nickel is the iron ore limonite, which often contains 1-2% nickel. Nickel's other important ore minerals include garnierite, and pentlandite. Major production sites include the Sudbury region in Canada (which is thought to be of meteoric origin), New Caledonia in the Pacific, and Norilsk in Russia. Because of nickel's slow rate of oxidation at room temperature, it is considered corrosion-resistant. Historically, this has led to its use for plating metals such as iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver. About 6% of world nickel production is still used for corrosion-resistant pure-nickel plating. Nickel-plated items are noted for provoking nickel allergy. Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements that are ferromagnetic around room temperature. Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is chiefly valuable in the modern world for the alloys it forms; about 60% of world production is used in nickel-steels (particularly stainless steel). Other common alloys, as well as some new superalloys, make up most of the remainder of world nickel use, with chemical uses for nickel compounds consuming less than 3% of production. As a compound, nickel has a number of niche chemical manufacturing uses, such as a catalyst for hydrogenation. Enzymes of some microorganisms and plants contain nickel as an active site, which makes the metal an essential nutrient for them...

Mining for Gold in Haiti: Haiti Helped or Exploited by U.S., Canadian Mining Companies?
 
06:19
Learn more: http://pulitzercenter.org/projects/haiti-gold-mines-foreign-companies-investment-government-distribution-wealth-poverty After years of rumors that gold mining companies were exploring in Haiti, Canadian and U.S. gold mining corporations now confirm they have permits to mine gold in more than 1,000 square miles in northern Haiti. Haiti's new prime minister says the estimated $20 billion worth of minerals in Haiti's hills could help liberate it from dependency on foreign aid and rebuild from the devastating 2010 earthquake. But many worry the gold mines will be a boom for foreign investors and a bust for local Haitian communities. Democracy Now! speak to Jane Regan, lead author of "Gold Rush in Haiti: Who Will Get Rich?" The report by Haiti Grassroots Watch was published Wednesday in The Guardian and Haïti Liberté. "You've got a perfect storm brewing whereby you're looking at giant pit mines in the north, in a country that's already environmentally devastated, and giant pit mines being run by Canadian and American companies," Regan says. "Most of the money that's made and most of the gold that's dug up will go straight north." (Modified from the original excerpt provided by Democracy Now!) This report is part of Pulitzer Center-sponsored project "Haiti: Sitting on a Gold Mine" (http://bit.ly/LSCNtf).

Top 10 Biggest Bitcoin Mining Companies Bitcoin miners are critical to Bitcoin and its protection. Mining, as soon as performed at the average home pc, is now normally finished in big, specialised warehouses. These warehouses typically direct their hashing power toward mining swimming pools. Mining swimming pools are businesses of cooperating miners who comply with share block rewards in percentage to their contributed mining hashing power.Bitcoin miners can transfer mining swimming pools without problems by means of routing their hash power to a one of a kind pool.

Another Large Silver Miner is Getting Out of the Silver Mining Business?
 
08:46
Long time primary silver miner, Hecla Mining, recently announced the takeover of Klondex Mines http://ir.hecla-mining.com/file/Index?KeyFile=392644009. Klondex has 3 producing gold mines and is not a silver miner. With this acquisition, Hecla's revenues will now be primarily from gold mining (at 50% of their total revenues) while only 30% of total revenues is now from silver mining. Jason outlines in the video how Nolan Watson confirmed this trend 2 weeks ago in his new interview that primary silver mines are NOT economic compared to primary gold mines. Many of the larger primary silver miners like: Fresnillo, Coeur D'Alene Mining (CDE), Hecla Mining and Silver Standard (now SSR Resources) are all moving much larger percentages of their total annual revenues into gold mining and away from silver mining. At just above $16/oz when this video was recorded, we are not at a silver price where other than Mag Silver's massive mine that new primary silver mines can be economic. In 2013, Hecla Mining start moving their revenues away from silver with their acquisition of Aurizon Mines and their producing gold mine in Quebec http://ir.hecla-mining.com/file/Index?KeyFile=17249854 Please visit the Wall St for Main St website here: http://www.wallstformainst.com/ Follow Jason Burack on Twitter @JasonEBurack Follow Wall St for Main St on Twitter @WallStforMainSt Commit to tipping us monthly for our hard work creating high level, thought proving content about investing and the economy https://www.patreon.com/wallstformainst Also, please take 5 minutes to leave us a good iTunes review here!

The Homestake Mine was a deep underground gold mine located in Lead, South Dakota. Until it closed in 2002 it was the largest and deepest gold mine in North America. The mine produced more than 40 million troy ounces (approximately 1.25 million kilograms) of gold during its lifetime. * * * * * * * * * * * * * * * History of the Homestake Mine: The Homestake deposit was discovered by Fred and Moses Manuel, Alex Engh and Hank Harney in April 1876, during the Black Hills Gold Rush. A trio of mining entrepreneurs, George Hearst, Lloyd Tevis, and James Ben Ali Haggin, bought it from them for $70,000 the following year. George Hearst arrived at the mine in October 1877, and took active control of the property. Hearst had to haul in all the mining equipment by wagons from the nearest railhead in Sidney, Nebraska. Arthur De Wint Foote worked as an engineer. Despite the remote location, an 80-stamp mill began crushing Homestake ore in July 1878. The partners sold shares in the Homestake Mining Company, and listed it on the New York Stock Exchange in 1879. The Homestake would become one of the longest-listed stocks in the history of the NYSE (Con Edison's original name was New York Gas Light and was listed in 1824). Hearst consolidated and enlarged the Homestake property by fair and foul means. He bought out some adjacent claims, and secured others in the courts. By the time Hearst left the Black Hills in March 1879, he had added the claims of Giant, Golden Star, Netty, May Booth, Golden Star No. 2, Crown Point, Sunrise, and General Ellison to the original two claims of the Manuel Brothers, Golden Terra and Old Abe, totaling 30 acres. The ten-stamp mill had become 200, and 500 employees worked in the mine, mills, offices and shops. He owned the Boulder Ditch and water rights to Whitewood Creek, monopolizing the region. His railroad, Black Hills & Fort Pierre Railroad, gave him access to eastern Dakota territory. By 1900, the Homestake owned 300 claims, on 2000 acres, and was worked by more than 2000 employees. In 1901, the mine started using compressed air locomotives, replacing the mules and horses by the 1920s. Charles Washington Merrill introduced cyanidization to augment mercury-amalgamation for gold recovery. "Cyanide Charlie" finally achieved 94 per cent recovery. The gold was shipped to the Denver Mint. By 1906, the Ellison Shaft reached 1,550 feet, the B&M 1,250 feet, the Golden Star 1,100 feet, and the Golden Prospect 900 feet, producing 1,500,000 tons of ore. A disastrous fire struck on 25 March 1907, which took forty days to extinguish after the mine was flooded. Another disastrous fire struck in 1919. In 1927, company geologist Donald H. McLaughlin used a winze from the 2,000 level to demonstrate ore reached the 3,500 foot level. The Ross shaft was started in 1934, a second winze from the 3,500 foot level reached 4,100 feet, and a third winze from 4,100 feet was started in 1937. The Yates shaft was started in 1938. Production ceased from 1943 until 1945, due to Limitation Order L-208 from the Government. By 1975, mining operations has reached the 6,800 foot level, and two winzes were planned to 8,000 feet.

Planetary Resources, The Asteroid Mining Company
 
07:49
I’m going to give an overview of Planetary Resources and explore the potential for asteroid mining. Planetary Resources, PR for short, will have their Arkyd-6 imaging satellite launched from the Indian Space Research Organization’s PSLV rocket in the coming weeks. The launch of the Arkyd 6 will bring PR one step closer to their goal to develop and deploy the technologies for asteroid mining. How does Planetary Resources plan to mine asteroids? Let’s find out! Welcome to NeoScribe, researching the future for you, so you don’t have to. If you’re new to my channel, I cover topics such as space exploration, robotics and ALL things future. So if you want to know how cool life will be in the future, hit the subscribe button, and notification bell, so you don’t miss out. Alight, our journey starts with the asteroid, 1903 LU also known as 511 Davida. It is the 7th largest asteroid in our solar system with a diameter of 167 to 192 miles or 270 to 310 km. Davida was discovered by Raymond Smith Dugan in 1903, and it will blow your mind. We will get to that a little later, but for now, let’s visit Asterank.com; which is a scientific and economic database of over 600,000 asteroids created by Ian Webster and acquired by PR in 2013. Here it is, we can see the inner half of the solar system, the outer orange ring is the orbit of Jupiter. The teal colored ring is the orbit of Earth. And then there are all these tiny white dots, glowing like specs of dust. Each of those dots are actual asteroids, simulated accurately, according to time which you can see is sped up in the upper right of the screen. Now let’s click on Most Valuable, and look to the left of the screen. On the top of the list, we see Davida. Next to its name is 1903’s estimated value of $15 QUINTILLION dollars. Unless you’ve played AdVenture Capitalist, you probably aren’t familiar with QUINTILLIONS. A QUINTILLION has 18 zeros behind it. $15 Quintillion is so much money, it would take GDP of all the countries in the world at $78 Trillion, 197,213 years to make $15 Quintillion! S0, Planetary Resources, PR, has their eyes set on the treasures of space. PR’s mission is to mine near-Earth asteroids for raw materials, ranging from water to precious metals. They aim to develop cost-effective exploration technologies, and initiate prospecting missions and target resource-rich asteroids that are easily accessible. PR believes mining asteroids could bring in billions of dollars annually to the global economy. The effort will tap into the high concentration of precious metals found on asteroids and provide a sustainable supply to the ever-growing population on Earth. PR was founded in 2009, in a shroud of secrecy, under the name of Arkyd Astronautics to hide their asteroid mining intentions. It was founded by Peter Diamandis, Eric Anderson and Chris Lewicki and is headquartered out of Redmond WA. They are backed by a handful of billionaire investors, including Google’s co-founder Larry Page, Google’s CEO Eric Schmidt, former Microsoft chief architect Charles Simonyi, and Ross Perot Jr. The company also has Avatar director James Cameron, former astronaut Tom Jones, and planetary scientist Sara Seager as advisers.

National Security, Rare Earth Elements & The Thorium Problem
 
23:00
"The only operating rare earth mine in the United States sends all of their valuable resources to China for processing. Congress does not know this. They think this [mining] company is supplying the U.S. value chain, [and] is supplying the military. It is in-fact, the opposite. They are part of the Chinese monopoly. They're taking powder and shipping it to China, and it comes back as a magnet, or an alloy, or a bolt-on component." - Jim Kennedy To address this issue, contact your legislators to support H.R.4883 https://www.govtrack.us/congress/bills/113/hr4883 Why can't Molycorp, Lynas or any other 'western' rare earth company succeed? China's production and market advantage in Rare Earth Elements (REE) is largely the result of NRC and IAEA "Source Material" regulations with unintended consequences. Source Material: Materials containing any ratio or combination of Thorium and Uranium above .05%. Producing or holding these materials within the regulatory threshold (.05%) requires extensive and wide-ranging licensing, storage, transportation, remediation disposal and compliance costs, including prohibitive liability and bonding issues. Consequently any potential supplier of byproduct / co-product rare earth resources that would be designated as "source material' disposes of these valuable resources to avoid liability and compliance issues. NRC / IAEA regulations regarding "Source Material" played a key roll in undermining the economic viability of all 'western' rare earth producers and are a critical factor in China's current 'market advantage'. Producers like Molycorp and Lynas, with low Thorium deposits, can never compete with China. Resources are abundant and available: U.S mining companies currently mine as much as 50% of global Rare Earth Elements demand every year. But these resources are diverted in tailings lakes or are redistributed back into the host ore body, due to NRC and IAEA regulations defining Monazite and other Thorium bearing rare earth resources as "Source Material". H.R. 4883 would solve the "Thorium Problem" by creating a federally chartered multinational Thorium Energy and Industrial Products Corporation ("Thorium Bank"). Privately funded and operated, this would decouple thorium from rare earth production. The Thorium Corporation would also have Congressional Authority to develop Thorium energy systems and industrial products. Environmental regulations are not scaled back... rather this enables thorium to be stored safely & securely, rather then being treated as "waste". https://www.govtrack.us/congress/bills/113/hr4883 H.R. 4883 thus also addresses the U.S. Weapons Systems current 100% Dependency on China for Rare Earths. http://thoriumenergyalliance.com/downloads/TEAC6/USWeaponsChinese.pdf Federal Legislation governing Strategic Materials, 10 USC 2533b, does not specify rare earths, but includes metal alloys containing limited amounts of manganese, silicon, copper, or aluminum, chromium, cobalt, columbium, molybdenum, nickel, titanium, tungsten, vanadium, nickel and iron-nickel, cobalt, Titanium and Zirconium alloys. Federal Regulations require that these materials be melted in the U.S. Most of these materials are utilized in rare earth alloys, magnets and components in the defense industry. The bill does NOT reclassify thorium. It does NOT alter current environmental protection. It simply resolves "The Thorium Problem" which cripples United States domestic rare earth mining, processing and value-adding processes.

Mountaintop Removal Coal Mining US Group Attacks Chinese Coal Company
 
02:01
A group in the United States called the Tennessee Conservative Union released an advertisement on Monday. The ad supports proposed state legislature that would ban mountain top removal for virgin peaks over 2,000 feet. But behind the ad is concern that a Chinese owned mining company, which has surface rights to about 48 square miles, would cause damage to Tennessee's mountains. [ADVERTISEMENT] "Tennessee has become the first state in our great nation to permit the red Chinese to destroy our mountains and take our coal. The same folks who hold our debt, hack our businesses, and have the worst conservation record in the world." Triple H Coal Company was bought by Chinese state-owned Guizhou Gouchuang Energy Holdings Group last year. This was the first Chinese acquisition of a US coal company, and a top Chinese CEO in the coal industry said Chinese coal companies were interested in further acquisitions. While TCU is worried about the destructive practice of mountain top removal, it is also concerned over Chinese companies with a poor environmental record acquiring US assets. [ADVERTISEMENT] "We're proud that Tennessee is a red state, but just how red are we willing to go?" Environmentalist group Appalachian Voices points out that while the coal is mostly sent to other US states now, it may not be that way for long. Last year the US sent 12% of US coal overseas, and as alternatives to coal become cheaper in the US, the group predicts, that percentage will increase. It also warns that if the coal industry becomes more international, the profits from Tennessee coal will go overseas while the pollution will stay at home.

OPEN PIT MINING OF COPPER IN THE AMERICAN SOUTHWEST 1960s MOVIE  57284
 
37:52
Produced by the Marion Power Shovel Company, this fascinating movie looks at copper and copper mining in the 1960s, when the American mines were at peak production and financial troubles loomed. The film looks at the future of mining, including the development of efficiencies to keep mines in business. Open pit mining techniques are shown, with a focus on the Southwest. At 2:00, Bingham Canyon and the Utah Mining Company pit (also known as the Kennecott Copper Mine) is seen. At 2:40, various open pit mines are seen which use either trucks or trains to remove ore. Although they are not named, it's likely that one of them is the Phelps-Dodge mine at Bisbee, Arizona. At 5:40, exploratory core drilling is shown. At 6:30, exploration programs are shown including at 6:43, an engineering team that maps mine development. Various drill systems are seen at 9:00, including the rotary drill. At 10:30, preparations are seen towards using explosives with the burying of dynamite and detonators for excavation. At 12:12, loading of explosives is seen with an emphasis on safe handling. At 14:51, a cage drill is shown in use allowing rocks to be drilled in the field (without being moved by shovels) for explosive removal. At 16:00, a small 4.5 yard bucket shovel is shown being used to move blast debris. At 16:00, a 6-yard loading shovel is seen. At 17:49, overburden waste from the pit is loaded on a train so that it can be moved and dumped at a remote area. At 18:50, a 13-yard shovel is seen in use with a large truck also in use. As the narrator explains, these large size equipment is needed to lower unit costs of copper, and are an economic necessity given the modern financial conditions. At 19:52, the motorized wheel principle of new types of mining trucks is seen, and the narrator comments that next generation trucks will carry over 100 tons of ore. At 22:55, a grader is seen working the mine roads, and the narrator comments about how tires wear out so quickly on the job that they account for up to 1% of mining costs. At 24:30, railroad trains are shown on the move at a mine, moving 60-125 ton per car loads. The narrator comments further on the use of railroads in pit mining. At 26:30, a large shovel is seen loading a train, sprinkling the loads with water to hold down dust. The large boulders in the loads make this type of work dangerous. At 27:16, ore loads are dumped into a crusher at a mill site. At 27:40, a rail waste dump into a slag pile is seen. At 28:00, a train-based grader is used to clear tracks of debris. The narrator notes that the mining railroads are some of the busiest in the USA and the world. At 28:44, new tracks are installed due to various demands, and mechanized railroad ballast systems are used for fast track installation. At 31:20, a skip hoist is seen being used to take ore from a deep, small pit to the surface. At 32:50, a series of leeching ponds is seen, with water percolated through the ponds to precipitate copper. At 34:00, a machine shop is seen at the mine, providing repair and maintenance services at the mine. At 35:40, a heavy repair part is unloaded at the mine using a power shovel. At 36:00, a research laboratory is seen at work, developing new uses of copper in the atomic and other industries. At 36:40, the IBM Ramac computer is seen. The IBM 305 RAMAC was the first commercial computer that used a moving-head hard disk drive (magnetic disk storage) for secondary storage. The film ends with a shot of a heap of pennies, with the narrator noting that the industry is working hard to expand production to fulfill future needs. The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine, is extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation in the world and produced more copper than any other mine in history – more than 19 million tons. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.6 miles (970 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres (770 ha). Marion Power Shovel Company was an American firm that designed, manufactured and sold steam shovels, power shovels, blast hole drills, excavators, and dragline excavators. The company was a major supplier of shovels for the construction of the Panama Canal. Founded in Marion, Ohio in August, 1884 as the Marion Steam Shovel Company, the company grew through sales and acquisitions throughout the 20th century. The company changed its name to Marion Power Shovel Company in 1946 to reflect the industry's change from steam power to diesel power.

Golden Gamble. Gold mining in the Philippines, a dirty business
 
25:41
More films about the Philippines: https://rtd.rt.com/tags/philippines/ - The use of child labour in the Philippine’s Paracale, or ‘Goldtown’, is widespread - Extracting gold involves diving into mud-filled shafts and using toxic mercury - Poverty and lack of alternative jobs force people into this highly dangerous work - Many die young due to work accidents or breathing problems, others develop chronic illness The Philippines’ town of Paracale was dubbed “Goldtown” for its rich deposits of the precious metal. Despite government attempts to regulate mining, illegal pits are still commonplace. They lack even the most basic health and safety and workers are exposed to toxic mercury fumes. Dirty water causes skin diseases and they live with the constant threat of being buried alive. Workers continue to take these risks day after day, because there is no other source of income. Many of the gold miners are children whose families can’t afford to send them to school. Some gold is panned on the surface, but a lot has to be extracted from underground. To do that, prospectors dive into narrow, mud-filled shafts, uses snorkelling masks and long tubes too breathe. If the mine collapses, they have no chance of escape. They have a saying here, ‘while you’re down the mine, you have one foot in the grave’. Several miners have already died that way, others from respiratory diseases caused by inhaling mercury fumes. The toxic metal is used in gold extraction with no safety precautions, so it poisons the air, the ground and the water, causing long-term harm to the whole community. Another danger to the inhabitants of Paracale comes from disused mines, abandoned and left open, waiting for unsuspecting victims to fall in. The business takes its toll on workers, their families and the community. They have been known to demonstrate, demanding safer working conditions, better pay and other job opportunities, but change is slow. Meanwhile, extreme poverty among people who produce one of the world’s most precious metals leaves them no option but to continue with this pitiless occupation.

Best Bitcoin Mining Company 2017: Hashing24, Genesis Mining Or Galaxy Mining?
 
22:20
Best bitcoin mining company 2017: hashing24, genesis mining or galaxy mining?Let’s calculate which one is the best cryptocurrency mining company and who has the best offer for your money for bitcoin mining. Update: hashing24 is a confirmed scam. Subscribe to the Crypto Mining channel: ➤https://www.youtube.com/c/cryptominingchannel?sub_confirmation=1 ►Example of 3000GH/s ☆Hashing24 : $598.5 lifetime contract + $0.00033 per GH/s (x 3000 = $0.99 daily x 30 = $29.7 monthly). So that’s a yearly maintenance fee of $356.4 ↳Total cost for 3 years : $1667.7 ↣You rent the equipment ☆Genesis mining: $450 lifetime contract + $0.00028 per GH/s (x 3000 = $0.84 daily x 30 = $25.2 monthly). So that’s a yearly maintenance fee of $302.4 ↣You rent the equipment ↳Total cost for 3 years : $1357.2 ☆Galaxy mining: $500 in total for a 3 year contract with compounding feature Only with galaxy mining and genesis mining of the three have the possibility to mine other coins. Genesis has dash mining, ethereum mining, litecoin mining, monero mining and zcash mining while galaxy mining currently has ethereum, zcash and expanse mining. But more cryptocurrencies will be added in the future. ↣You OWN the equipment! NO cloud mining! ↳Total cost for 3 years: $500 Let’s calculate which one has the best offer for your money for mining cryptocurrencies other than bitcoin. ►Example of 20MH/s ☆Genesis mining: $600 ($30 per MH/s) for a 2 year contract ☆Galaxy mining: $500 retail contract for 17.8MH/s ($28,09MH/s) for a 3 year contract (because of repurchases longer as long as mining is profitable). ►Example of 100MH/s ☆Genesis mining: $2799 ($27.99 per MH/s) and no maintenance fee, 2 year contract ☆Galaxy mining: $2500 for a 3 year wholesale mining contract for 92.5MH/s + bonus 18.5MH/s = 111MH/s. For contracts like this above $500 you first have to purchase a membership of $400 before you can enjoy higher contracts at better rates and wholesale price. The membership is for life, and you can buy as many contracts as you want, bitcoin contracts as well as multimining contracts. So $400 + $2500 = $2900 ($2900 : 111MH/s = $26.13per MH/s if you calculate the cost of the one time member package). Price per MH without calculating the membership : $2500 : 111MH/s = $22.52 per MH/s! Clearly galaxy mine is the most generous and secure cryptocurrency mine in the world! ♚Galaxy mining♚ is crowned King of cryptocurrency mining contracts.

Chinese State-owned Mining Companies Exploit Zambian Miners, Says Rights Group
 
02:39
For more news visit ☛ http://english.ntdtv.com Follow us on Twitter ☛ http://twitter.com/NTDTelevision Follow us on Facebook ☛ http://me.lt/9P8MUn Human Rights Watch released a report that severely criticizes Chinese copper mining companies in Zambia for exploiting miners and ignoring workers' rights. According to the report, Chinese state-owned mining corporations are consistently violating Zambian laws and international regulations. Here's more. Chinese state-owned copper mining companies in Zambia are being severely criticized by an international rights group. A Human Rights Watch report released on November 3rd states Chinese mining firms frequently violate Zambian and international labor laws and regulations. [Matthew Wells, Human Rights Watch, Africa Division, Researcher]: "We found that there were consistent threats to fire employees that refuse to work in unsafe places underground... the Chinese manager would actually threaten the worker that he'd be fired if he didn't go ahead." The 122-page report titled "You'll Be Fired if You Refuse" contains a comprehensive account of how these companies exploit Zambian miners. The violations include poor health and dangerous working environments, and long shifts—from 12 to 18 hours of hard labor. The report identifies China Non-Ferrous Metals Mining Corporation (CNMC)—a Chinese state-owned corporation—as the parent company of the four mining companies. It's compiled from recent interviews with miners from three on-site visits. The report cites the miners' saying "They just consider production, not safety. If someone dies, he can be replaced tomorrow." Miners report managers bribing or threatening workers to stop them from reporting accidents to the Zambian government Mines Safety Department. The head of Human Rights Campaign in China says the Chinese regime exports its bad practices. [Hu Jun, China's Human Rights Campaign Head]: "Communist China is now spreading its (predatory) concept a number of ways via social disruption overseas." They focus only on establishing rapport with the foreign government. [Liu Kaiming, Institute of Contemporary Observation Director, Shenzhen]: "It's the habit of the Chinese enterprises. They might have continued their habit in China. Their habit was to create good relations with the government... They don't care about the situation of the workers, or the opinion of the community." Human Rights Watch Africa director Daniel Bekele says many of the violations found in Zambia's Chinese state-owned mines reflect the same kind of abuses as those in China.

Top 10 Countries With The LARGEST Gold Reserves!
 
10:12
Check out these 10 countries with the largest gold reserves in the world! This top 10 list features some of the richest and wealthiest countries on earth that have tons of gold bars stacked up somewhere! Subscribe For New Videos! http://goo.gl/UIzLeB Watch our "SURPRISING And Interesting Facts About Money!" video here: https://youtu.be/ONpChSPqVc4 Watch our "Most AMAZING Discoveries With A Metal Detector!" video here: https://youtu.be/45JveYKafVo Watch our "Most EXPENSIVE Diamonds In The World!" video here: https://youtu.be/RcZATf3Lmb0 10.) India According to the World Gold Council, the Bank of India currently holds 557.7 tons of gold. It is one of the largest stores of gold in the world! This makes up 9.9 % of the country’s total foreign reserve. Foreign exchange reserves is money or other assets held by a nation’s central bank so they can back the national currency. India, home to 1.25 billion people, is the number one largest consumer of the precious metal. Furthermore, India is one of the most reliable drivers of global demand. For example, India’s festival and wedding season, which runs from October to December, has historically been a major market for gold. And probably, one of the most interesting facts about India and gold is that India rarely invests much in gold. This is because as a country, India operates under the belief that buying gold leads to a deficit. And their belief must be proving right as things also seem to be improving for India. For instance, if you look at the last few years, India has increased its gold reserves from 557.74 to 557.77. While this might not seem like a lot, India is also at its highest point in history! In addition to what the country holds, Indian households which are considered the world’s largest hoarders of gold, hold a record 23,000-24,000 tons, which is worth about $800 billion. 9.) Netherlands In the past few years, the Netherlands has held 52% of its foreign reserve in gold. The Netherlands has a reported 612.45 tons. In 2016 it was reported that the bank was looking for a place to store all its gold because they were going to renovate the vaults and needed to moving it. The Dutch central bank is planning to move the country’s gold reserves from the center of Amsterdam to a new complex called the Cash Center. Like most countries, Dutch gold is also held in banks around the world to reduce risk. Security measures to guard the gold 24/7 have become a problem in Amsterdam. 189,000 kilos of gold will be moved at the beginning of 2022. Maybe this is one reason that over the last decade and a half, the Netherlands was selling off tons of gold in order to reduce its reserve. However, there weren’t that many buyers out there and they sold less than the country wanted. More recently the country has had less ambition to sell gold. Currently, the country holds the same amount of tons, 612.45 that they have over the last few years. However, the country has increased its percentage of foreign reserves to 61.2 %. 8.) Japan Japan is another country which had been increasing its gold reserves since the 1960’s. Their official gold holdings were reported at 765.2 tons. About 2.4% of Japan’s gold today is in foreign reserve. Historically, Japan has always held a bit more gold than other countries. This was true until 2011, when they began to sell some of their reserve in order to pump money into the economy after the tsunami and the following Fukushima nuclear disaster. But even with selling, Japan’s central bank has been one of the most aggressive practitioners of quantitative easing. For example, in January of 2016, it lowered interest rates below zero, which has helped fuel demand in gold around the world. 7.) Switzerland Prior to 1997, Switzerland was steadily building its gold reserves. In 1997, the decision was made to sell some of those reserves to bolster the Swiss currency and diversify the foreign reserves. The percent of foreign reserves in Switzerland is currently 6.7 %. Switzerland actually has the world’s largest reserves of gold per capita and currently has reported 1,040 tons. Over time, many citizens in the country started to feel like the bank was getting rid of too much gold. They then banded together with the “Save the Swiss” movement. However, once everyone was able to vote in 2014, the vote came to a no, and gold continued to be sold. During World War II, Switzerland became the center of the gold trade in Europe, making transactions with both the Allies and Axis powers. Today, much of its gold trading is done with Hong Kong and China. Around last year, the Swiss National Bank made a $5.9 billion profit, reportedly from its gold holdings.

How Copper is Mined and Refined: "A Story Of Copper" 1951 US Bureau of Mines

Support this channel: https://www.patreon.com/jeffquitney more at http://scitech.quickfound.net/geology_news_and_links.html "Tells the story of the mining and manufacture of copper from the crude ore to the finished product. lots of footage of giant machines, some blasting." Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Copper_extraction_techniques Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Copper extraction techniques refers to the methods for obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). To do this, the ore is crushed. Then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being electrolysis. For economic and environmental reasons, many of the byproducts of extraction are reclaimed. Sulfur dioxide gas, for example, is captured and turned into sulfuric acid — which is then used in the extraction process... History The earliest evidence of cold-hammering of native copper comes from the excavation at Çaÿonü Tepesi in eastern Anatolia. The radiocarbon date is 7250 ± 250 BCE. Among the various items considered to be votive or amulets there was one that looked like a fishhook and one like an awl. An archaeological site in southeastern Europe (Serbia) contains the oldest securely dated evidence of copper making at high temperature, from 7,000 years ago. The find in June 2010 extends the known record of copper smelting by about 500 years, and suggests that copper smelting may have been invented in separate parts of Asia and Europe at that time rather than spreading from a single source. Copper smelting technology gave rise to the Copper Age and then the Bronze Age. Concentration Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock. The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution, where the rock is crushed to produce small particles... Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary (supergene) and primary (hypogene), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit... Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production)... The copper is refined by electrolysis. The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid. Cathodes are thin rolled sheets of highly pure copper or, more commonly these days, reusable stainless steel starting sheets (as in the IsaKidd process). A potential of only 0.2–0.4 volts is required for the process to commence. At the anode, copper and less noble metals dissolve. More noble metals such as silver, gold, selenium, and tellurium settle to the bottom of the cell as anode slime, which forms a salable byproduct. Copper(II) ions migrate through the electrolyte to the cathode. At the cathode, copper metal plates out, but less noble constituents such as arsenic and zinc remain in solution unless a higher voltage is used. The reactions are: At the anode: Cu(s) → Cu2+(aq) + 2e− At the cathode: Cu2+(aq) + 2e− → Cu(s)...
