Processes In Extraction Of Gold

Gold extraction - Wikipedia

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.

There are four main processes of gold extraction: Mechanical processes for preparing and washing the ore. Preparation of the ores, with simultaneous or subsequent amalgamation. Chemical extraction-processes. Smelting of certain ores.

Gold Extraction / Mining | Goldfo

Extraction of Gold by the Amalgam Process. The amalgam process is the oldest technical method of extracting gold and was used in antiquity. With the amalgam process the gold bearing rock is likewise crushed to fine sand. Afterwards mercury is added to the rock dust. Gold has the property that enables it to join to the surface of the mercury.

Extraction of gold using cyanide - nzqa.govt.nz

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.
