Artisanal and Small-Scale Gold Mining Without Mercury

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.

1.Introduction cdn.who.int

Artisanal and small-scale gold mining (ASGM) is, in general terms, the exploitation of smaller gold deposits by individuals, small groups or small cooperatives (1). ASGM is usually labour intensive, using no or limited mechanization and typically with low recovery rates. The sector is often characterized by low levels of capital, productivity, and job security, and limited access to land and

The Mercury Problem in Artisanal and Small-Scale Gold Mining

Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated-often with a torch or over a stove-to distill the mercury and isolate the gold. Mercury release from tailings and vaporized mercury exceed
