cyanide. The process of extracting gold from ore using cyanide solution (usually NaCN but can also be KCN) is called cyanidation. The affinity of cyanide for gold means it will be preferentially extracted compared to other metals (e.g. iron). Cyanidation is adversely affected by the presence of free sulphur or sulphide minerals in the ore.
