Abstract: The beneficiation technology research on a carbonaceous shale copper-cobalt-nickel ore whose carrier ore is carbonaceous shale.Different minerals have complex paragenetic relationship and disseminated fine grain size was conducted.Based on the process mineralogy and beneficiation tests,the technological process including pre-decarbonization-preferential flotation of copper-cobalt-nickel activital flotation from copper tailings was determined.The study achieved the effective elimination of ore of easy floating gangue which affect the flotation on copper-cobaltnickel by optimizing for the process structure and regime of agent,resulting in good floatation indexes.
