Origin and consumption of mercury in small-scale

2006-1-1 · Mercury (Hg) is used by small-scale gold miners in more than 50 developing countries, where the accompanied releases affect human health and the environment. The objectives of this paper are to summarize present use of Hg in artisanal and small-scale mining (ASM) worldwide, reveal the origin of part of the Hg used by the gold miners, and propose appropriate actions to reduce the resulting Hg

History Of Mercury Use in Products and Processes |

Humans have been mining mercury ore from the deep earth (the “lithosphere”) since at least the Roman times. The Romans operated a mercury mine in Spain with prisoner and slave labor. They used mercury as a pigment in their paint; mercury-containing paint has been found in Roman homes buried by the volcanic ash of Mount Vesuvius in 79CE. The use of mercury in paint has continued into the modern area, although in recent history, mercury

2009-7-4 · Mercury was widely used to in California gold mines to extract the precious metal from solid ore. Between the years 1850 and 1981, more than 220,000,000 lb of mercury was used in mining in that state. Mercury and other metallic elements form an amalgam, or a solution of the solid metal in the liquid mercury metal. The dissolved material can be recovered by evaporating the mercury. Mercury is still used this way in some mining

2011-12-22 · Mercury exists in nature primarily as elemental mercury or as a sulfide and is found in the earth's crust at approximately 0.5 parts per million. Atmospheric exposures occur from outgassing from rock or through volcanic activity. Human sources of atmospheric mercury include coal burning and mining (mercury and gold in particular). Atmospheric elemental mercury settles in water, where it is converted by microorganisms into organic (methyl or ethyl) mercury
