  • PyriteGold Recovery in Copper Rougher Flotation Tailings

    unintentional pyrite flotation is undesirable in a CuAu ore flotation circuit due to the detrimental effect on Cu final grade. Therefore, in order to improve final concentrate grade, pyrite depression strategies ( aeration, sulphite, cyanide addition, etc.) have been used over the years to minimise pyrite recovery.
