Low pH cyanidation of gold

Lime is used in CIP/CIL slurries to increase the pH, which partially stops the formation of aqueous hydrogen cyanide. Hydrogen cyanide gas can be evolved directly from the pulp surface or purged from the leach tank in oxygen or air that is sparged into the tanks to provide oxygen for the dissolution of gold.

Cyanidation of gold clay ore containing arsenic and …

2009-3-27 · The extraction process of gold and silver from the gold clay ore containing arsenic and manganese was investigated. With the conventional technique, the leaching rates of gold and silver are 78.23% and 49.02%, respectively. To eliminate the negative effects of arsenic and manganese on cyanidation and increase the gold and silver leaching rates, a novel catalyst was added.

What is Gold Cyanidation? (with picture)

The cyanidation process begins after the gold has been discovered and the raw ore separated from the ground, often by explosive means. The ore is ground up to better facilitate the leaching process. Breaking up the ore into finer pieces is called heap leaching. Processing the ore immediately without crushing it is known as dump leaching.

Gold Tailings Reprocessing Technology

Xinhai usually adopts the all-slime cyanidation + CIP in the gold extraction from old tailings. The gold tailings after cyanidation are treated by dry stacking. That is a technology that recycles the filtrate to realize the water resources recycling in processing plants with pressure filtration process, and get rid of most cyanide in the tailings.
