Artisanal and Small-Scale Gold Mining Without Mercury

In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Why does mercury dissolve many metals (such as gold

Mercury does not actually dissolve metals, it reacts with them in a process called amalgamation (Amalgam (chemistry)). The formation of mercury alloys is not quite like a reaction but rather a mixture (alloy) of metals similar to table salt going

How Is Gold Formed? Origins and Process

Gold sank to the Earth's core during the planet's formation. It's only accessible today because of asteroid bombardment. Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It's easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold via decay.

Mercury Retorting Mineral Processing & Metallurgy

In California the total loss of mercury varies from 1/5 to 1 oz. of mercury per ton of ore crushed, the mean being about ½ oz. per ton. Most of the mercury is lost as such and not in the form of amalgam, as is proved by the fact that where the largest proportion of mercury is fed into the battery the greatest loss takes place but the highest percentage of gold is recovered.

Mercury easily amalgamates with other metals, such as gold, silver, zinc and cadmium. Dental amalgam is an alloy that is made of 43 to 54% mercury combined with a percentage of silver, tin, zinc and copper. Mercury forms very useful compounds with other elements. Some of these mercury compounds are mercuric oxide, mercuric sulphide, mercuric chloride, and mercuric

History Of Mercury Use in Products and Processes | Mercury

By 1000 CE, mercury was used to extract gold by amalgamation. The mercury surrounds the gold, forming shiny pellets that workers then burn. The mercury evaporates, leaving the purified gold. This process is still practiced by artisanal small-scale gold mining operations today, exposing over 10 million of workers to the toxic element and

Mercury (element) Wikipedia

Gold and silver mining. Historically, mercury was used extensively in hydraulic gold mining in order to help the gold to sink through the flowing water-gravel mixture. Thin gold particles may form mercury-gold amalgam and therefore increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s.
