The oxide ore has a much higher grade than the mixed and sulphide ores but contributes less to the resource (Broughton et al., 2002). The preferred method for the flotation of oxide and mixed copper ores is sulphidisation. The reagents are typically sodium sulphide (Na 2 S) and sodium hydrosulphide (NaHS). Slug sulphidisation, which uses a ...

Direct whole ore leach (WOL), as opposed to the traditional but inefficient oxide ore flotation and concentrate leach, is now being applied to many copper oxide ores particularly those in the revitalized DRC. At current metal and acid prices, the much improved metal recoveries more than off-set the cost of the additional acid needed in the leach.

A preliminary copper flotation recovery model was generated at a fixed 25% copper concentrate grade with test results as summarized below: Recoveries of greater than 95% for copper into a 25% copper concentrate are possible. Copper sulfide minerals are well-liberated for rougher recovery via flotation at P 80 of 150 µm.

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 – e.g. the Kolwezi Tailings Project. Similarly, because cobalt follows iron during smelting, some of the copper smelter
