2009-10-22 · Extraction of gold by means of cyanidation is based on the ability of gold to form a stable water-soluble double salt KAu(CN) 2 when combined with potassium cyanide in association with oxygen. The pulp resulting from the crushing of gold ore consists of larger crystalline particles, known as sands, and smaller amorphous particles, known as silt.
