Gold Processing With Mercury

Mercury Usage in Gold Mining and Why It Is a Problem

22-07-2019· First, mercury is mixed with the materials containing gold. A mercury-gold amalgam then is formed because gold will dissolve in the mercury while other impurities will not. The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. This process does not result in gold …

Mercury in Gold Processing - ScienceDirect

01-01-2016· Mercury is used to extract gold by forming a gold–mercury amalgam in artisanal and small-scale gold mining (ASGM). Almost all of this mercury is lost to the environment when the amalgam is heated to purify the gold, at an estimated 1400 metric tons per year . It is estimated that 12–15% of the world's gold is produced in this manner.

17-08-2020· The technique of amalgamation, alloying with mercury to improve the recovery of gold, was discovered at about this time. The colonization of South and Central America that began during the 16th century resulted in the mining and refining of gold in the New World before its transferal to Europe; however, the American mines were a greater source of silver than gold.

Environment: Cyanide-free gold processing solution …

Currently, around 75% of gold extracted from ore is processed using the hazardous chemicals of cyanide or mercury, which are toxic to humans and the environment. These chemicals are often contained in large storage tanks and, once used, expelled into large tailing dams that can potentially leach into the local surrounds or, worse, burst as we’ve seen in recent years in Brazil and Canada.
