Gold History of Use Mining Prospecting Assay amp Production

Gold History of Use Mining Prospecting Assay amp Production

Extraction of gold and other precious metals from their ores by treatment with mercury is called amalgamation. Gold dissolves in aqua regia a mixture of hydrochloric and nitric acids and in sodium or potassium cyanide. The latter solvent is the basis for the cyanide process that is used to recover gold from low-grade ore.

Sep 07 2017 At current gold prices this is worth about US600. Both smelter treatment charges and oxidation or bio-leach costs are at least 200t of concentrate and payablesrecovery in the 90 range so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price but in the current gold price and cost .
