Gold cyanidation 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. Due to the highly poisonous nature of cyanide, the process may be considered controversial and its

The leach circuit comprises 22 tanks with a total volume of 44 000 m3 in two parallel streams that allows for a total retention time of 7 hours. Calcium cyanide is
Outotec offers complete cyanide leaching plants irrespective of the material quality. Free-milling gold materials are cyanide leachable and so are the refractory
Leaching & Adsorption. A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved.
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
