Silver processing BritannicaArtisanal and Small Scale Gold Mining Without Mercury

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve This is called inquartation and the separating of silver and gold by leaching with nitric acid is referred to as partingIn 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
