Dissolving Gold in Mercury
 
06:11
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

GH13 MERCURY GOLD AMALGAMATION
 
08:20
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.

gold amalgamation
 
01:29
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.

How to mine gold and live to tell about it
 
03:08
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.

Small-scale gold mining exposes thousands to mercury poisoning
 
00:46
Sign up for a free trial of News Direct's animated news graphics at http://newsdirect.nma.com.tw/Reuters.aspx Next month 140 countries will sign the U.N. Minamata Convention, which aims to regulate the use of mercury to reduce rates of contamination in countries where small-scale gold miners operate. The convention is named after the world's biggest mass mercury poisoning, which occurred 60 years ago in Japan. The cause of the poisoning was identified only 30 years later as a local plastics factory that was dumping mercury into a nearby bay. Mercury is a neurotoxin that affects the cerebellum, the part of the brain that controls movement. It also harms the kidneys and other organs. Hand tremors, coordination problems and headaches are among the early symptoms of mercury intoxication, which can also cause birth defects. Small-scale miners, who are responsible for producing about 15 percent of the world's gold, typically use mercury to extract gold from rock or soil, putting themselves and the environment at risk of mercury poisoning. Approximately 10 to 15 million people are involved in the practice worldwide, including 3 million in Indonesia. Miners wash crushed gold ore with mercury by rivers with their bare hands, poisoning themselves and waterways. Afterwards the gold, now an amalgam of mercury and gold, is brought to smelters which burn away the mercury, poisoning people and the environment nearby.

Using mercury to recover gold is not a recommended practice, however this tube-retort fills the need for gold prospectors and small scale miners who encounter mercury and amalgam while conducting mining operations. It is recognized that mining operations around the world still use mercury to recover gold. The hope is that this YouTube video will be an effective tool for educating responsible recovery practices - this is the safest and easiest method to separate the amalgam. This is a sustainable method as there are no chemicals to purchase nor replenish to recover the mercury from the amalgam. The exception being that a heat source must be supplied such as a propane or MAPP gas torch. There is no hazard to users due to over-pressurization of a chamber. There is very little chance of mercury vapor escaping the tube-retort if it is used properly. Inhalation of mercury vapor is the biggest hazard of any operation involving mercury. Stay Safe! Emphasis and priority is placed on the responsible and safe recovery of liquid mercury in order to keep it out of the environment. The left over gold is just a perk!

What is PAN AMALGAMATION? What does PAN AMALGAMATION mean? PAN AMALGAMATION meaning & explanation
 
03:33
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.
