Experimental research on beneficiation for a copper ore in Hunan

A copper ore in Hunan province was taken as the research object. In view of theore ore properties, the single flotation process was adopted. On the basis of the condition test, the small closed-circuit experiment was conducted ,obtaining the qualified copper concentrate with the copper grade of 26.15% and thecopper recovery of 90.75% and containing 89.68 g/t of silver, achieving the goal of comprehensive recovery. Good beneficiation indexes were obtained.
