Health risks of gold miners: a synoptic review

These problems are briefly documented in gold miners from Australia, North America, South America, and Africa. In general, HIV infection or excessive alcohol and tobacco consumption tended to exacerbate existing health problems. Miners who used elemental mercury to amalgamate and extract gold were heavily contaminated with mercury.

Mercury Usage in Gold Mining and Why It Is a Problem

Jul 22, 2019  How Mercury Is Used in Gold Mining. 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.

Mercury control in the cyanidation of gold ores

The control of mercury during gold cyanidation is of particular interest to the gold mining industry. Typically, mercury(ll) is released as cyano complexes during leaching and follows gold through the solution concentration and puriflcation step (carbon adsorption and electrowinning or zinc cementation). Ultimately, prior to the

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.
