Extraction of g using cyanide

Extraction of g using cyanide G is found in very low concentrations in the ore from which it is mined. To collect the g from the ore it needs to be separated from the other minerals in the ore. To do this the g needs to be made into a soluble form so that it can be separated from the other minerals as g is insoluble.
