Historically, mercury was used extensively in placer gold mining in order to form mercurygold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Largescale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and smallscale gold mining (ASGM), often clandestine, gold prospecting.
Gold mining describes the process of extracting ore – metalrich rock – from the earth''s crust. And, as with other minerals, there are a number of geological processes that are involved in forming these ore deposits. Modern gold mining predominantly takes place in areas where there is a significant concentration of goldbearing ore (ore ...
