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.

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

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.

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.

Kenya Miners Part 3: Mercury recovering gold from sluice cons, then burning to get salable gold
This is our third video in our five part series of our trip to Kenya to install a shaker table to help eliminate the use of mercury by the smalls scale gold miners. We met with Julius who is the president of the MICA gold mining cooperative and donated a shaker table to MICA to show the miners a different technology for gold concentration other than the use of mercury. Once the shaker table was set up the miners were amazed! The shaker table on average recovered 2-3 times more gold from the same material they had been processing with their blanket/burlap sluices and mercury use. The table can also process the material up to 10 times faster than the blanket/burlap sluices. The result being in some cases 30 times more gold for the miners in the same amount of processing time. Stay tuned for more videos of our trip to Kenya.

What is PATIO PROCESS? What does PATIO PROCESS mean? PATIO PROCESS meaning & explanation
What is PATIO PROCESS? What does PATIO PROCESS mean? PATIO PROCESS meaning - PATIO PROCESS definition - PATIO PROCESS explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. The patio process is a process for extracting silver from ore. The process was invented by Bartolomé de Medina in Pachuca, Mexico, in 1554. The patio process was the first process to use mercury amalgamation to recover silver from ore. It replaced smelting as the primary method of extracting silver from ore at Spanish colonies in the Americas. Other amalgamation processes were later developed, importantly the pan amalgamation process, and its variant, the Washoe process. The silver separation process generally differed from gold parting and gold extraction, although amalgamation with mercury was also sometimes used to extract gold. Bartolomé de Medina was a successful Spanish merchant who became fascinated with the problem of decreasing silver yields from ores mined in Spanish America. By the mid-sixteenth century, it was well known in Spain that American silver production was in decline due to the depletion of high-grade ores and increasing production costs. The New Laws, prohibiting the enslavement of Indians, had resulted in higher labor costs as miners turned to wage labor and expensive African slaves. These higher production costs made mining and smelting anything but the highest grade silver ores prohibitively expensive, just as the availability of high grade ores was in decline. Bartolomé de Medina initially focused his attentions on learning about new smelting methods from smelters in Spain. He was approached during his research by an unknown German man, known only as "Maestro Lorenzo," who told him that silver could be extracted from ground ores using mercury and a salt-water brine. With this knowledge, Medina left Spain for New Spain (Mexico) in 1554 and established a model patio refinery in order to prove the effectiveness of the new technology. Medina is generally credited with adding "magistral" (a copper sulfate) to the mercury and salt-water solution in order to catalyze the amalgamation reaction. However, some historians assert that there were already sufficient copper sulfates in the local ores and that no additional magistral was needed. Regardless of whether or not Medina's contribution was entirely original, he promoted his process to local miners and was able to obtain a patent from the Viceroy of New Spain. As a result, he is generally credited with the invention of silver amalgamation in the form of the patio process. Silver ores were crushed (typically either in "arrastras" or stamp mills) to a fine slime which was mixed with salt, water, magistral (essentially an impure form of copper sulfate), and mercury, and spread in a 1-to-2-foot-thick (0.30 to 0.61 m) layer in a patio, (a shallow-walled, open enclosure). Horses were driven around on the patio to further mix the ingredients. After weeks of mixing and soaking in the sun, a complex reaction converted the silver to native metal, which formed an amalgam with the mercury and was recovered. The amount of salt and copper sulfate varied from one-quarter to ten pounds of one or the other, or both, per ton of ore treated. The decision of how much of each ingredient to add, how much mixing was needed, and when to halt the process depended on the skill of an azoguero (English: quicksilver man). The loss of mercury in amalgamation processes is generally one to two times the weight of silver recovered.

How gold-diggers ruin their health
I filmed this in Ghana in 2013. Between 2007 and then, a frenzied gold rush took place, spearheaded by thirsty, illegal Chinese immigrants. The type of gold mining they engaged in is called small-scale or alluvial mining, which by law is available only to Ghanaian citizens. The Ghana government expelled most of the illegal Chinese after a turbulent period. Meanwhile, the price of gold has plunged, and the allure has lost its luster. When small-scale miners find gold in usually tiny amounts, they amalgamate the gold with mercury, which is highly toxic. After the amalgamation, the mercury is burned off, exposing the miners to the dangerous fumes.

What is BORAX METHOD? What does BORAX METHOD mean? BORAX METHOD meaning - BORAX METHOD definition - BORAX METHOD explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ The borax method is a technique of artisanal gold mining, which uses borax as a flux to purify gold concentrates. By using borax, no mercury flour is produced, hence gold recovery increases. The borax method of gold extraction has been used by artisanal gold miners in the Benguet area north of Manila in the Philippines for more than 30 years. Some believe it was in practice as early as the 1900s. The method is increasingly being seen as a safe alternative to the widespread use of toxic mercury in artisanal gold mining today. About 30% of the world's mercury emissions comes from small scale mining. Efforts are being made to revive the method and spread its use. As of 2012, around 15,000 artisanal gold miners in a small area of Luzon, the main island in the northern portion of the Philippines, use this method exclusively. The mineral is inexpensive and easily available, and the miners have reportedly found that more gold is recovered through its use. In contrast to the use of mercury (which relies on amalgamation of the impurities) this method relies on borax's ability to lower all the minerals' melting points, including that of gold. Since the gold is usually the heaviest of these minerals, it allows for concentrating the gold on the bottom of the crucible. The process requires considerably less heat than conventional refining methods, which can be obtainable even in remote locations (using charcoal). After the ore is crushed into a fine powder, it's lightly panned to leave only the heaviest minerals in the pan. It's then thoroughly mixed by three times (by volume) as much of borax and a few drops of water. This mixture is then heated until the whole mixture is molten, after which molten droplets of gold collect on the bottom of the crucible.

Heap Leaching of Gold and Silver Ores
HEAP LEACHING OF GOLD & SILVER ORES Heap leaching is the process to extract precious metals like gold, silver, copper etc, from their ore by placing them on a pad (a base) in a heap and sprinkling a leaching solvent, such as cyanide or acids, over the heap.. This process dissolves the metals and they collect at the bottom of the pad. The metal is then further processed. This methodology is mostly used for low-grade ores, and the basic processing steps involve crushing and sometime grinding.. The stages for heap leaching can be described as: 1. Ground Preparation and pad construction: Here the soil on a slightly sloping ground is compacted and covered by an impermeable pad (can be made of plastic). 2. Ore stacking: Then the crushed ore is stacked in the form of big heaps. Amount of fines is decreases as low as possible to improve permeability. 3. Then the leaching agent such as cyanide or acid is sprayed over the heap. 4. As, the reagent passes through the heap; the valuable metals get dissolved in it. 5. The solution containing metal is drained from the heap and collected in a pond and the solution is sent for subsequent process for metal recovery.. Is there any investors who are interested to cooperate for gold mining area in my village, actually typical of the material in my village is good proses by Heap Leaching Method process..

Eric Clark's Travel Videos - Idrija Slovenia - Full Mercury Mine Tour! Watch the entire Tour! From web site https://www.culture.si/en/Idrija_Mine_Museum "Thanks to having the second largest mercury mine in the world the town of Idrija was for centuries considered to be the centre of scientific and technological progress in the region. The administration of the Idrija Mercury Mine was housed in the Gewerkenegg Castle (16th century) which dominates the town. Today it houses the Idrija Municipal Museum, which together with the Idrija Mine Museum takes care of the region's rich technical, geological, technological, ethnological, and cultural heritage. The Idrija Mine Museum is managed by THE Idrija Mercury Heritage Management Centre. In 2012 the Heritage of Mercury. Almadén and Idrija project was submitted to UNESCO and both cities entered its World Heritage List. Mercury mining in Idrija The history of mining in Idrija dates back to 1490. Only the Almadén mercury mine in Spain was bigger and dates back to the Roman times. Both towns were so famous that their names were used in North America for the mining towns of New Idria and New Almadén. Until World War I the Idrija Mercury Mine was one of the best technically equipped mines in Europe. By burning cinnabar ore, the mercury miners of Idrija mined over 13 per cent of the world production of this ore. In 500 years Idrija exported 107,700 tons of this liquid metal. In 1986 the decision was made to close the mine for commercial, geological, and ecological reasons. It finally closed in 1995 but some of its shafts and facilities have remained open for tourists. Today the company's main task is to close down the mine and to manage the consequences of 500 year mining, that is to secure the shafts and to monitor the pollution of the environment. UNESCO World Heritage List The mercury mining heritage in Idrija (together with the oldest theatre house in Slovenia, the warehouse, the city hall, the old town square, the science secondary school, the Gewerkenegg Castle, etc.) was successfully nominated to become a UNESCO world heritage protected site in 2012. The first project for the candidature was prepared in 2007 under the title Idrija on the Mercury Route of the Intercontinental Camino Real together with Almadén (Spain) and San Luis Potosí (Mexico). The development of the "Mercury Route" as part of the Intercontinental Camino Real was greatly influenced by the 1554 discovery of amalgamation in America. The process used mercury in acquiring silver and gold from ore and sparked a major increase in the demand for mercury (Idrija, Almadén). The metal was foremost exported to Mexico where it was used in silver mines. This discovery influenced the global development of manufacture, technology, and trade in mercury as well as facilitated an intensive transfer of technological knowledge and changes in the global economy, social relations, science, and culture. Museum sites The Idrija mine ore deposit is unique on the world. Quoting a Soviet geologist Vladimir Ivanovich Smirnov (1910–1988): "I have seen many ore deposits in different parts of the world and some of them quite complex. But I openly admit that such a complex geological structure as in Idrija, I haven't yet seen. Without any doubt this is structurally one of the most complex endogenous ore deposits in the world." The Mine Museum has a rich geological collection with more than 800 different samples of ore and mineral from Idrija mercury ore deposit on display at the Idrija Municipal Museum. Anthony's Shaft is the oldest part of the mine, today also one of the oldest preserved mine entrances in Europe. Named after Anthony of Padua, a patron saint of miners and protector from mine accidents, the shaft was dug back in 1500, soon after mercury was first discovered. The museum tour is 1,300 metres long in an authentically preserved mine. It starts in the 18th-century Šelštev House where miners used to take the equipment early in the morning before entering the mine. Here visitors to the mine watch a multivision show in the former call-in room, than professional guides take them through shafts and illuminated galleries with life-size mannequins which illustrate the various mining jobs to the unique underground Chapel of the Holy Trinity, dating from the mid-18th century, the time of the greatest prosperity for the Idrija mine. The shaft was opened for the public in 1994. At the entrance, visitors are given raincoats to wear during the tour and are greeted with the typical miner's greeting srečno ("good luck"), which gets its true meaning when entering the shaft. Francis's Shaft was sinked 1792 and is named after the Roman-German Emperor Franz Joseph the Second (1792–1806). It is a big transport shaft with the only preserved huge exporting machine Siemens-Stuckert, still in operating condition."
