Artisanal and Small-Scale Gold Mining Without Mercury

2020-11-16  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 ...

History Of Mercury Use in Products and Processes

2013-1-16  By 1000 CE, mercury was used to extract gold by amalgamation. The mercury surrounds the gold, forming shiny pellets that workers then burn. The mercury evaporates, leaving the purified gold. This process is still practiced by artisanal small-scale gold mining operations today, exposing over 10 million of workers to the toxic element and ...

Artisanal and Small-Scale Gold Mining in Nigeria

2011-7-11  Artisanal and small-scale gold mining (ASGM) has long been practiced in Nigeria and around the world. Bolstered by historically high gold prices, a lack of viable alternative livelihoods, and a ready – if expensive – supply of mercury, there has been a resurgence of ASGM activities in northern Nigeria in

Impact of Gold mining on the Environment and Human

The study of gold sites in the Migori Gold Belt, Kenya, revealed that the concentrations of heavy metals, mainly Hg, Pb and As are above acceptable levels. Tailings at the panning sites recorded values of 6.5–510 mg kg−1 Pb, 0.06–76.0 mg kg−1 As and 0.46–1920 mg kg−1 Hg. Stream sediments had values of 3.0–11075 mg kg−1 Pb, 0.014–1.87 mg kg−1 As and 0.28–348 mg kg−1 Hg ...
