This method is largely becoming deprecated as the yield of Gold is often Extraction of gold using cyanide Home » NZQA,2015-8-24 · Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
