Detailed Plant For E Tract Gold With Cyanide

UTILIZING CYANIDE RECOVERY TECHNIQUES IN THE CESL .

Cyanide in solution is combined with gold ore and leaches the metal to form a soluble cyanide gold complex. The gold is then typically adsorbed onto activated carbon for downstream recovery. The resulting barren solution, still containing cyanide but absent of gold, can then be recycled for reuse and leaching of new ore.

buy cyanide to extract gold - andanteschool

Sodium cyanide is used mainly to extract gold and other precious metals in mining industry. This application exploits the high affinity of gold(I) for cyanide, which induces gold metal to oxidize and dissolve in the presence of air (oxygen) and water, producing the salt sodium gold cyanide (or gold sodium cyanide) and sodium hydroxide.
