Cobalt Recovery By Flotation

cobalt recovery by flotation

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. the cobalt grade in the pyrite concentrate was 3,500 ppm co.,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.
