· Even the highly toxic cyanidation is an industrial process of gold production, whereas the artisanal miners use mercury for dissolving the gold traces from the collected mud, soil, and rocks. As an estimate, about 140 kg of cyanide and a massive consumption of 700 tons of water are required to produce 1 kg of gold (Mudd 2007 ).
