In the cyanide process for extraction of gold and silver

In the cyanide process for extraction of gold and silver from ores, the cyanide solution acts as a: (A) Reducing agent to reduce the gold and silver compounds in the ores into metallic states. (B) Leaching agent to bring the gold and silver into the solution as cyanide complexes and thus separate these metals from the ores.

Extraction of Gold

Cyanide-process The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well-known solubility of
