Nov 16, 2020 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 ...
However, based on the idea that gold in most alluvial ores is liberated, artisanal miners rarely invest in efficient comminution processes when processing colluvial or eluvial ores. They often use hydraulic monitors to create a slurry and then pump the ore pulp to a gravity concentration process as was common with Californian gold prospectors in the Gold Rush from 1848 to 1855 (Limbaugh, 1999) 30 .
