Extraction of gold using cyanide

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 Get price

Process of Cyanide Gold Extraction

Here I present an Process EXAMPLE of Gold Extraction Cyanide in which the cyanidation feed consists of a pyrite concentrate floated after the selective flotation of a copper-gold concentrate The pyrite concentrate is reground to 90% minus 325 mesh and aerated in a high-lime solution prior to cyanidation It contains 99% sulphides of which 10 to 20 percent is pyrrhotite and 0 3 to 0 7% Get price
