| Abstract: | A combined beneficiation and metallurgy technique was introduced to process a typical cobalt-bearing copper oxide ore from Congo (DRC), a copper-cobalt ore containing 3.22% copper and 0.045% cobalt. The whole set of processing technique consists of pretreatment by asynchronous flotation, leaching of copper-cobalt oxide concentrate followed by flotation of leaching residue, and fluidized bed roasting plus leaching of copper-cobalt sulfide concentrate. The whole flow test shows that the copper and cobalt recovery can attain 81.23% and 59.19%, respectively, indicating that copper and cobalt resources can be recovered efficiently. |
