Cyanide Leaching Chemistry Gold Cyanidation

Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately. Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.
