Extraction of gold using cyanide - Home » 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 Gold English Wikipedia, the free encyclopediaGold is a soft, heavy, yellow metal.It is a chemical element.Its chemical symbol is Au.Its atomic number is 79.
