Cyanidation of a copper-gold ore

 · A free milling gold ore, which contains 0.4% copper as chalcopyrite, was treated with cyanide. In the pre-leaching, the kinetics of oxidation of soluble sulphides are not an accurate indication for the length of the treatment. Efficient gold leaching is achieved only ...

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex. It is the most commonly used leaching process for gold extraction.[1] Production of reagents for mineral processing to ...

The recovery from sulfide ore is poor because the cyanide preferentially leaches the sulfide minerals rather than the metals, and cyanide is consumed by the formation of thiocyanate. These ores are subject to a concentration processes such as flotation, followed by a secondary process to oxidize the sulfides, thereby limiting their interaction with the cyanide during leach ing .

Grinding

The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out. Grinding is always carried out under wet conditions, with about 70% solid mixture in water.
