The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – eg the Kolwezi Tailings Projectprocess flowsheet into which the new separation process is inserted After the initial leaching process of the nickel ore or concentrate, and subsequent liquid/solid separation, purification is needed to remove: a) Copper, if present in commercial quantities, by solvent extractionA New Process for Cobalt Nickel Separation• Heavy medium separation is the process of separating copper ores by a specific medium (ferrosilicon) density • Testwork on copper ores at a size range of 76 mm+ 6 mm and a medium density of 28 demonstrated that 49% of the mass can be rejected whilst only losing 14% ofInnovations in Copper Mineral Processing Technology
