The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to 'see' the gold in the leaching process.

A process called "pressure oxidation" is used to oxidize the gold-bearing materials. The oxidized material is mixed with a cyanide solution in large tanks inside the mill. The gold dissolves in the cyanide. The dissolved gold is then collected onto activated carbon, and the cyanide solution is sent to a cyanide-detox unit.

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.
