cyanide in manganese ore processing

After the preparatory stage prior to the completion of the separating, the gold in the ore is dissolved with an oxygenated cyanide solution. The two main agents used in the leaching process are cyanides such as sodium cyanide, potassium cyanide, and protection of alkali such as lime. The second process, washing. The ore is subjected to cyanidation leaching to produce a slurry composed of a gold-containing …
