The plants which process the ores to produce a higher value product, either cathode or intermediate, use acid leaching. The flowsheet is largely the same for all plants (Sole & Cole, 2002), and summarised in Figure 1. After ore preparation, a reductive acid leach is used to solubilise the copper, cobalt and

Sep 01, 2020 A specific cobalt flotation circuit is run at KCM’s Nchanga concentrator. 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.

Nov 01, 2019 For Cu–Co ores in the DRC, oxidised ore deposits have historically been the main source of Cu–Co as they are relatively simple to process, mainly by leaching/solvent extraction/electrowinning. As high-grade oxidised Cu–Co ores become depleted, importance is placed on the mining of low-grade disseminated ores.
