  • Cobalt and copper recovery from the ancient flotation
    Cobalt and copper recovery from the ancient flotation

    The ancient flotation tailings from Lefke, Cyprus, have a potential for non-ferrous metals such as cobalt and copper from more than 9.5 million tons of reserves containing 0.38% Cu, 0.032% Co, and 22.6% Fe. Recovery of cobalt and copper from these tailings can provide great benefits from economic and environmental perspectives

    The effect of copper sulphate addition on the recovery

    The copper sulphate was always added prior to collector addition. As specified in the experiments performed, a dosage of either 30 g/ton or 90 g/ton was used. A copper sulphate dosage of 30 g/ton is the stoichiometric amount required to react with the thiol collectors. At 90 g/ton copper sulphate there would be excess copper ions in solution
