Extraction of gold using cyanide NZQA

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 To make gold soluble sodium cyanide NaCN is added and the
