Investigation on Copper Flotation from a Complex Copper

The mineral processing flow sheet and reagent system of flotation copper minerals from alarge copper sulfide deposit in Yunnan were fully investigated. The results indicated that the optimum conditions for flotation of copper minerals from the material were identified as follows: grinding fineness of 80%(-0.074mm), dosage of CaO 800g/t, butyl xanthate 100g/t.Under such condition, a copper ...
