Froth flotation of oxide minerals by sulphidization is a widely used technique in the metallurgical industry. Sulphidization of oxide minerals renders them amenable to recovery using a xanthate collector. Both under and over addition of sulphide have a detrimental effect on mineral recovery. Much of the sulphide is consumed through oxidation
