A copper oxide ore treatment by flotation
The ore containing 0.77 % copper, the main metal minerals in the ore are hemesite, pyrite bomite, covellite, malachite, the main gangue minerals in the ore are quartzite, dolomite, plagioclase, Chlorite, calcite.And the copper oxidation ratio of the ore is 45.5%, According several flotation tests, finally found that the optimum reagents dosage are: butyl xanthate 90g/t as collector, pine oil 35g/t as foaming, sodium sulphidel000g/t, lime3000g/t, and the flow-sheet is one stage of roughing, three stage of cleaning and two stage of scavenging operationg in the close circuit under the grinding fineness is 85%-0.074mm.Satisfactory results had been obtained as the grade of is 18.06% with recovery 80.01%.
