COBALT PROCESSING DEVELOPMENTS K G Fisher

2011-7-5  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.

Innovations in Copper Mineral Processing Technology

2019-5-1  • Heavy medium separation is the process of separating copper ores by a specific medium (ferro-silicon) density. • Testwork on copper ores at a size range of -76 mm+ 6 mm and a medium density of 2.8 demonstrated that 49% of the mass can be rejected whilst only losing 14% of copper an upgrade of 169% .
