Dec 10, 2018 · Artisanal and small-scale gold mining (ASGM) in the Amazonian countries has undergone important technological improvements in recent decades. Nevertheless, this type of mining is largely associated with the use of rudimentary, low-tech and often manual methods, and inefficient gold recovery ( Hilson and Van Der Vorst, 2002, Veiga et al., 2014a ). Small-scale gold mining in the Brazilian Amazon …… Read more

the mercury problem in artisanal and small‐scale gold mining

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… Read more

Mar 01, 2021 · Abstract. The recent spate of gold discoveries in Zambia has necessitated the formulation of a coherent strategy to promote sustainable exploitation of gold for social-economic development. In this paper, a cooperatives strategy for artisanal and small-scale gold mining in Zambia is presented. The strategy exploits a state gold buying programme to promote three elements, namely, formalisation of …… Read more

This process of extracting the gold from ore is done without the use of mercury or cyanide. While these green gold mining techniques might be sufficient for the artisanal and small-scale gold mining sectors, such as those in Mongolia, greener gold mining options are still in the exploration phase for larger mining operations.For larger companies to adopt greener gold mining techniques, they… Read more

alternatives to mercury use insmall-scale gold mining

December 30, 2020. Posted in LOCAL solutions. In Zimbabwe elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, resulting in the formation of the mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process is very dangerous and can lead to significant mercury exposure with serious environmental and health …… Read more
