Chemical leaching makes use of the chemical properties of gold to leach it from ore, concentrate, or tailings. This process is mostly used in large scale mining operations but has been increasingly adopted in small scale mining because of its high gold recovery rate and low cost. The best practices for chemical leaching are a combination of pre-concentration and mill leaching, as they lead to the least amount of

26/06/2020  Artisanal and small-scale gold mining (ASGM) happens in almost all mineral active African countries. Gold is mined in two ways; one on hard rocks where gold found embedded in quartz vein is extracted using simple tools. Mined ore is then crushed either manually using a hammer or by a crusher. The ore is then grinded using ball mill to produce dust-size product. This process is done to liberate

The Mercury Problem in Artisanal and Small‐Scale Gold ...

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 ...
