Artisanal and Small-Scale Gold Mining (ASGM), as defined by the United Nations Environment Program, is gold mining conducted by individual miners or small enterprises with limited capital investment and production costs [3,17,18,19].

It is an illegal or unregulated form of artisanal small scale gold mining (ASM) and could either be in a stand-alone mining mode, a stand-alone processing or gold extraction mode or in a simultaneous mining and processing

Recent upsurges in the demand for mercury may be in response to market conditions, as both the rising price of gold and falling demand for diamonds has driven an increase in ASGM activity [8,19]. Figure 3. Mercury (Hg) cycle in a typical artisanal and small-scale gold mining (ASGM) process

Nov 16, 2020 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

the Requirements for a clean technology in small scale gold mining (1) - the technology must be technically efficient (more than the traditional methods) Technical-economical criteria: - the equipment, if possible, needs to be manufactured locally - long life span - simple and safe handling and maintenance (also by less qualified personnel)

Our vision is to enable small-scale gold miners to achieve the same gold recovery rates as large-scale miners but with a lower cost, scalable, mobile processing plant. Small-scale miners can find it difficult to operate profitably. In Australia alone, 85% of gold tenements are inactive. This trend can be reversed and they can now better afford to compete with the large-scale miners

May 11, 2018 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.
