Thermal roasting behavior and kinetics of African cobalt
African cobalt-rich copper sulfide ore (CRCS) is an important copper-cobalt resource. The CRCS mainly contains chalcopyrite (CuFeS 2), pyrite (FeS 2), and carrollite (CuCo 2 S 4).In our previous study, activated roasting was used to treat CRCS, converting CuCo 2 S 4 into sulfate that is easy to leach Cu and Co. It was found that the kinetics of …
