  • Copper LPF Leach Precipitation and Flotation Process

    Approximately 40% of the total copper occurs in non-sulphide form. Metallurgical tests conducted on the ore showed that sulphidization was ineffective to recover a significant part of the oxidized copper. However, the leach- precipitation-flotation process, commonly referred to as LPF, was shown to be economically feasible.
