Dissolving Gold in Mercury
Follow me on Instagram: https://goo.gl/5oQiWQ Follow me on Twitter: https://goo.gl/uCmnV4 ----------------------------------------- Okay, so we are not truly dissolving the gold, we are actually forming an alloy between the gold and the mercury (called an amalgam). This process is not only cool to look at, but it also is really useful to extract gold from ore. The gold-mercury amalgam can then be isolated and the mercury is boiled off or removed chemically. This leaves behind relatively pure gold. Outro music: https://soundcloud.com/sorrysines

Amalgamation Gold Process
Amalgamation of gold in this simple to use drum machine tools in the arrest of the mineral content of gold. Gold amalgamation process is done very simply, where the gold mineralized rocks incorporated into the equipment of this machine, and then pulverization of rock will occur in the machine, so the rock will be destroyed and become like flour. For the incorporation of mineral rocks of gold in the machine, then add to the mercury in the machine, so that the amalgamation will occur between the mercury with gold mineral VISIT OUR BLOG http://miningeducation.blogspot.com/2012/01/amalgamation-process-gold.html

This unsafe method of amalgamation of gold with mercury was filmed by me in the gold-rich Ashanti region of Ghana, where poor young men and women perform small-scale, surface alluvial mining. Although panning for gold has been going on for centuries in Ghana, an intense period of this alluvial mining took place between about 2005 and 2012, when illegal Chinese miners flocked to Ghana in the thousands and employed young Ghanaian men and women to do the brunt of the physical work. The richer Chinese used huge excavators to dig deep into the earth, forming pits that scarred the landscape and unearthed heavy metals. Small-scale gold mining in Ghana has reportedly declined recently, but the mercury-gold amalgamation and extraction shown is still common. Many young Ghanaian miners are unaware or dismissive of the dangers of inhaling mercury fumes. Obviously, the method shown is NOT recommended, but I captured it as part of the research for my novel GOLD OF THE FATHERS, to be released in April 2016, a murder mystery set in Ghana with illegal gold mining as its background.

सोना(Gold) कैसे निकाला जाता है? Process for Discovering, Mining & Refining Gold
धरती के अंदर तेल और गैस के भंडारों का पता कैसे लगाया जाता है? How to find oil and gas? Link : https://www.youtube.com/watch?v=IsgYLbhCUaA #gold #Gold_in_India #Gold_mining Some people cover their cars with Gold, some wear clothes made of gold wire, someone designs Gold their mobile , there are many people in the world who use gold in different way. women of India are also addicted to gold ornaments. people had bought gold to hide their money. But do you know how gold is formed inside the earth? What are the ways to find Gold? How Gold prepared? From which places of India does gold come out? Which countries is the largest gold source? How the gold came inside the earth or how? Humans would never have got the chance to be ashamed of gold. Millions of years ago when the earth was being built. Along with these extraordinary conflicts, billions of tons of molten gold and platinum fell into the center of the Earth and became part of its crude. But today the human race has become so clever that he is in search of everything and is in the process of getting it. So something like this Gold come on earth and today its prices are high. How to find Gold in Under Ground ? So this work happens in the same way as the oil and gas deposits in the ground are detected, in which ground penetration radar (GPR) is used to find out what is in the ground. In fact, it records the physical properties of the soil such as density, magnetic properties, registration, on which the graph is prepared and it is estimated that the core analysis is done under the soil, then the core analysis is done. Drilling it under the ground and removing a little debris and analyzing it. It gives accurate information about what is below. Apart from this, hidden property, metal, i.e. gold, silver, copper etc. are detected through VLF technology. For this the waves are sent within the ground. Once after hitting these waves, the VLF receiver creates an electromagnetic field around that object and produces a sequestration by collision the special metal. This kind of survey is carried out by the team of Archaeological Survey of India (ASI) and Geological Survey of India (GSI). There are 7 different ways to find gold. 1) break the rocks by exploding 2) Milling of stones 3) the process of wetting sand 4) process of cyanide 5) Amalgamation 6) Flotation So by this process, you can guess that finding gold is a very difficult task, this is the reason why gold prices are so high in the market. Gold is very solid and it is very difficult to actually make ornaments. Usually gold is found either in the form of alloy with either pale or silver or alone. It is also found in the form of Calvarites, Sylvainite, Petjite and Cranerite ores. And the gold which is extracted from the mine is in the form of ore, which is absolutely pure gold. Which places of India are extracted gold? Most of the production of gold in India is in the state of Karnataka, where gold is extracted from the mines called Kolar, Hutti and Uti. Apart from this, gold is also extracted from Andhra Pradesh and Jharkhand's Hirabuddin and Kendraakocha mines. If we talk about a mine of Jharkhand, then about 4 grams of gold is extracted from a ton of stone and on average, 7 kg of gold is extracted from a mine here every year. The biggest gold mines in the world. In which Kimberley mine is in Africa, after Grasberg mine which is in Papua, Carlin Nevada mine which is in the US, weladero mine which is in Argentina and the writer's quarry is in Papua New Guinea. 5 countries that produce the most gold or produce gold. 1. China which has been ahead in gold production for many years, China produces 426 tons of gold in about a year. But his government has seen a decline of 6 percent in the past year due to the efforts taken to fight pollution and increase environmental awareness. However, due to the excavation of several mines in existing projects, this year's production is expected to begin. 2. Australia Australia produces 295.1 tons of gold in a year. The mineral industry is more than half of Australia's total exports and generates about 8 percent of GDP. 3. Russia A large part of European gold comes from Russia, which has been increasing its production every year since 2010. Russia produced 17 tons more than last year, And Russia produces 270 tonnes of gold every year. 4. United States America also pulled 8 tonnes more gold this year compared to the previous year. Where the production was supported by Project Ramp-up in the Long Canyon Project in Nevada and the Hail project in South Carolina. And the United States produces 230 tonnes of gold every year. And about 78 percent of the US gold comes from Nevada alone. 5. Canada Fall of a glacier in north British Columbia in Toronto, Sebrija Gold stumbled upon an important golden area and estimated to be estimated at 780 metric tons. Canada produces 175 tons of gold every year.
How to mine gold and live to tell about it
As of 2011, Colombia was the largest per capita mercury polluter in the world. One of the major sources of mercury pollution is from artisanal and small-scale gold mining, due to the mercury used to extract the gold from other products in a process called whole ore amalgamation. Mercury from burning of the gold-amalgam is a major contributor of mercury air pollution; these mercury byproducts also contribute to water pollution via settling into the water and dumping directly into the water from in-situ amalgamation. One source of mercury poisoning in humans is via ingestion of methylMercury from fish, which results from microorganisms in the water converting mercury to methylMercury. MethylMercury can reach dangerous levels in the local population who consume fish as a primary staple in their diet. Mercury poisoning causes serious health effects: birth defects, neurological damage, and autoimmune disorders. We aim to reduce all the mercury exposures by eventually moving to mercury-free gold production techniques. One way is to improve concentration by using sluices, centrifuges, shaking tables, and magnets, that help separate the gold from other products. Another way is gravity only techniques such as panning, direct smelting, or chemical leaching. These processes are actually more effective at yielding higher amounts of gold than whole ore amalgamation, but miners lack education about effective methods and toxic effects of mercury use. In contrast to Fancy Pants Gold Mining, most (63%) of Colombia’s gold mining is done illegally which makes it very difficult to regulate.

gold amalgamation
Amalgamation cylinder, as a type of internal amalgamating equipment that is widely used in gold processing plant, is used to process heavy sand containing gold of gravel mine and gold concentrate of vein gold mine, presenting a gold recovery rate of higher than 98%. Amalgamation cylinder is used to recover the gold from ore concentrate, heavy sand and various ores. Although most of the gold in gold concentrate is in free form, the surfaces of gold grains are usually polluted to a greater or less extent, and some gold exists with other minerals or vein rocks in adherent form. . When gold concentrate is processed with amalgamation cylinder, steel balls are usually added to the cylinder for grinding operation to remove the film on gold grain surfaces and separate the gold grains from adherent bodies. When the heavy sand ore concentrate of free gold grains with clear surfaces is treated, we usually use light-duty amalgamation cylinder with extremely small quantity of steel balls. . When processing the heavy sand ore concentrate with high adherent body content and serious gold grain surface contamination, we usually use heavy duty amalgamation cylinder, for which 1-2 kg of steel balls need to be loaded for 1kg of heavy sand ore concentrate. . The loading quantity of concentrate and steel balls of amalgamation cylinder is related to material grain size and gold content. During non-alkaline medium amalgamation, heavy sand ore concentrate may produce magnetic mercury amalgam due to the interfusion of Fe substances. . Hence, internal amalgamation is usually operated in alkaline mediums. The quantity of lime is 2%-4% of loading capacity, and water quantity is usually 30%-40% of loading capacity; alternatively, the usual grinding concentration can also be used.

What is PAN AMALGAMATION? What does PAN AMALGAMATION mean? PAN AMALGAMATION meaning & explanation
What is PAN AMALGAMATION? What does PAN AMALGAMATION mean? PAN AMALGAMATION meaning - PAN AMALGAMATION definition - PAN AMALGAMATION explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The Pan amalgamation process is a method to extract silver from ore, using mercury. The process was widely used from 1609 through the 19th century; it is no longer used. The patio process had been used to extract silver from ore since its invention in 1557. One drawback of the patio process was the long treatment time, usually weeks. Alvaro Alonso Barba invented the faster pan process (in Spanish the cazo or fondo process) in 1609 in Potosí, Bolivia, in which ore was mixed with salt and mercury (and sometimes copper(II) sulfate) and heated in shallow copper vessels. The treatment time was reduced to 10 to 20 hours. Whether patio or pan amalgamation was used at a particular location often depended on climate (warmer conditions speeded the patio process) and the availability and cost of fuel to heat the pans. The amount of salt and copper(II) sulfate varied from one-quarter to ten pounds of one or the other, or both, per ton of ore treated. The loss of mercury in amalgamation processes was generally one to two times the weight of silver recovered. The Washoe process, a variation of pan amalgamation, was developed in the 1860s by Almarin B. Paul and others, to work the ore from the Comstock Lode in Nevada, United States (Washoe was an early name for the area; see Washoe Valley).:41 In the Washoe process, the copper pans were replaced by iron tanks with mechanical agitators. Each tank ("pan") was circular, and commonly held 1,200 to 1,500 pounds of ore that had been crushed to sand size. Water was added to make a pulp, and 60 to 70 pounds of mercury, along with one-half to three pounds each of salt (sodium chloride) and bluestone (copper(II) sulfate) were also added. A circular iron plate called a muller was mounted on a vertical shaft and lowered into the pan, and was rotated to provide both agitation and additional grinding. Heat was delivered to the pans by steam pipes. The iron filings worn from the muller and pan proved to be an essential ingredient in the process. A variation of the Washoe process was developed in the Reese River mining district around Austin, Nevada. The Washoe process was found not to work well for ores with arsenic or antimony sulfides, or with galena or sphalerite. In 1869, Carl A. Stetefeldt of Reno found that roasting the ore with salt converted the silver sulfides to silver chlorides, which could then be recovered in amalgamation pans. The process was introduced in the Reese River District in 1879, with great success. Other silver-mining districts using the Reese River process included Georgetown, Colorado, Caribou, Colorado, and Silver Cliff, Colorado.

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.

Upper Bralorne Mine Explore
Our exploration of one of the upper portals of the Bralorne mine in Bralorne BC. The Bralorne property is centred on a gold-quartz vein system. The Bralorne mine, comprising the King, Empire (or Ida May) and Crown workings, operated continuously from 1932 to 1971. Production during this period and from older operations totals 4.9 million tonnes of ore yielding 87.6 million grams of gold and 21.9 million grams of silver, for an average recovery of 16.1 grams per tonne gold and 4.03 grams per tonne silver (MINFILE 092JNE001). The property is a consolidation of 133 Crown-granted claims and fractions, many of which were staked in 1897. The staking began after the discovery of gold-bearing quartz veins on the north bank of the lower course of Cadwallader Creek (Cairnes, 1937). Access to the area at that time was 110 kilometres by difficult trail from the railway. The original lode claims were explored individually or in small groups (the Lorne and Pioneer groups of claims were staked in 1897) and by 1898 almost all the veins that would be mined had been found. Gold was first recovered by hand crushing and panning the oxidized quartz from surface exposures. Adits were developed on the promising leads and gold was won in quantity from the ore by improvising primative mills. At Lorne two 12-foot arrastres were erected driven by a 28-foot overshot water wheel to process in a few tons of ore per day and in 1900 a 5-stamp mill was set up to increase production. On selling the Pioneer property, Arthur Noel purchased the Lorne mine from William Sloan and Dan Hurley. Prior to this the Lorne, King and Woodchuck veins had been successfully worked by Mike Gaynor, Nat Coghlan, William Young, John Williams and E.J. Taylor. In 1910 Lorne Amalgamated Mines Company gained control of the King mine and the adjacent key ground that included the Lorne, Golden King, Woodchuck, Wood Duck, Telephone and Marquis Crown-granted claims. After some shallow surface workings were completed the No.3 adit-crosscut was driven 335 metres to intersect the King vein. Work on the property was facilitated in 1915 when the Pacific Great Eastern Railway reached Lillooet on the Fraser River. Supplies from the coast were then routed 90 kilometres westward by road following the Bridge River. By 1920 some 900 metres of underground drifts and crosscuts had been developed and about 150 kilograms of gold produced, however, increasing sulphide and arsenic content in the veins at depth made gold recovery by amalgamation too low to pay in so remote an area. In 1928 Lorne Gold Mines Limited (Stobie, Furlong and Company) was incorporated and acquired the Alhambra and Blackbird claims, the Empire mine on the Ida May claim and the Coronation mine workings to the southeast. Proceeds from the sale of stock were spent driving a 900-metre adit tunnel 800 feet (245 metres) below the surface showings and by 1929 the principal veins in the King mine were delineated but in 1930 underground development was suspended because of financial difficulties. A new mining era began in 1931 when Lorne sold 60% interest to Austin Taylor and Associates who then organized Bralorne Mines Limited and took control of the property. A 100-ton mill was installed employing blanket concentration and floatation, thus commencing a 40-year period of continuous production (Photo 1). In 1935 milling capacity was increased to 475 tons daily.
