Although the affinity of cyanide for gold is such that it is extracted preferentially, cyanide will also form complexes with other metals from the ore, including copper, iron and zinc The formation of strongly bound complexes such as those with iron and copper will tie up cyanide that would otherwise be available to dissolve gold
Inorganic cyanides are compounds which are salts of hydrocyanic acid Inorganic cyanides have the cyano group bounded to metal atoms They are all white solids, and soluble in water In acidic water, inorganic cyanides liberate gaseous hydrogen cyanide Inorganic cyanides are incompatible with isocyanates, nitrides and peroxides Due to their
Gold Cyanide Solution (Leaching Gold With Cyanide) Since the 1890's, cyanide has been used to recover gold from gold bearing ores And today, over 115 years later, most of the worlds gold is recovered with cyanide playing a large part in the beneficiation of the yellow precious metal
Resin bead size 10-14 mm Effect of salinity on ion exchange resins for gold cyanide 775 The decrease in ionic density (or the separation of 'active' sites on the resin) has been studied previously and has been shown to enhance the selectivity of strong base resins for gold cyanide [ 16]
