Artisanal and Small-Scale Gold Mining Without Mercury - EPA

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.

Determining Gold Balance In Refractory Gold Ores | Metallurgy | News

SRK completed several studies on gold-bearing, complex-sulfide ore feed and autoclave tailings from a mine on the Carlin trend in northern Nevada. Feed, mill and autoclave products were studied at different stages of an autoclave process to identify the reason for variable recovery in some ores. Under the standard.
