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.get price

OverviewIssuesOpportunitiesApproaches to supporting and formalizing artisanal miningOrganizationsCountry specificSee alsoFurther reading

Artisanal mining can include activities as simple as panning for gold in rivers, to as complex as development of underground workings and small-scale processing plants. In any of these circumstances, issues can stem from difficulties in achieving regulatory oversight of a large number of small operations (including issues such as security of land tenure for artisanal miners, to enforcement of environment, safety standards, and labour standards). get price

The Mercury Problem in Artisanal and Small‐Scale Gold Mining

May 11, 2018 The Mercury Problem in Artisanal Gold Mining. Mercury‐based artisanal and small‐scale gold mining (ASGM) causes more mercury pollution than any other human activity.1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.get price
