in placer mines, the g is recovered by gravity separation. for hard rock mining, other methods are usually used.
cyanide extraction of g may be used in areas where fine gbearing rocks are found. sodium cyanide solution is mixed with finely ground rock that is proven to contain g or silver, and is then separated from the ground rock as g cyanide or silver cyanide solution. zincis added to precipitate out residual · text under ccbysa licenseamalgamation process of gjul 27, · the use of aluminum dust, sodium sulphide, and charcoal as precipitants receives attention. g amalgamation process principles. the amalgamation process, which has been widely used in a variety of forms from earliest times, depends upon the wetting and alloying of metallic g
