Gold: History of Use, Mining, Prospecting, Assay & ProductionArtisanal and Small-Scale Gold Mining Without Mercury

Gold was produced in the southern Appalachian region as early as and perhaps as early as in southern California The discovery of gold at Sutter's Mill in California sparked the gold rush of -50, and hundreds of mining camps sprang to life as new deposits were discovered Gold production increased rapidlyIn 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.
