Sep 01, 2020 The ore from the Nchanga open pit contains pockets of ore with higher grades of cobalt, typically about 0.3 cobalt and 1.3 copper. This ore is processed in campaigns through the cobalt flotation circuit, which is illustrated schematically in Fig. 11. The concentrate typically contains about 16 copper and 4 cobalt.
Low grade sulfide ores are difficult to process due to their composite mineralogy and their fine grained dissemination with gangue minerals. Therefore, fine grinding of such ores becomes essential to liberate valuable minerals. In this research, selective flotation was carried out using two pitched blade turbine impellers with diameters of 6 cm and 7 cm to float copper and nickel.

Jan 01, 1991 The metal in question may be copper, nickel, zinc or in the case of the mines in Elliot Lake, uranium. At the Denison mine, up to 10 of the uranium is produced using bacterial means involving the leaching of low-grade pyritic ore in abandoned stopes. Another similar application concerns the leaching of low grade copper sulphide ores in heaps.

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the worlds current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation.
