gold cyanidation - wikipedia

in some ores particularly those that are partially sulfidized aeration prior to the introduction of cyanide of the ore in water at high ph can render elements such as iron and sulfur less reactive to cyanide therefore making the gold cyanidation process more efficient specifically the oxidation of iron to iron iii oxide and
