  • Cobalt and copper recovery from the ancient flotation

    Abstract 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.cobalt recovery by flotation greenrevolution.in,Post copper recovery, the conditions of flotation are altered in the subsequent stages to promote pyrite recovery.Cobalt recovery in the roughing phase was considerably higher than expected at 75.9%.
