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

Rcovery of gold in pyritic ores mine-engineer

Sulfide ores, and pyrites in particular, have caused and continue to cause difficulty in recovering the gold values from these ores. In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination.
