Copper sulphide ore mainly includes chalcopyrite, bornite and chalcocite, and the main beneficiation method is flotation.

The flowsheet describing the flotation processing of a copper ore containing chalcopyrite and molybdenite is shown in following figure . After grinding（by ball mill) and classification, pulp is fed to rougher flotation machine.The rougher tailings are thickened and sent to a tailings dam. The rougher concentrate is classified,and the oversize is reground. Hydrocyclone overflow is fed to cleaner flotation machine, and the cleaner concentrate is recleaned. Cleaner tailings are recycled back to rougher flotation, and the recleaner concentrate is thickened and sent to the molybdenum recovery plant for further processing. In this operation, the feed contains 0.32% Cu and 0.03% Mo. Rougher concentrate, cleaner concentrate, and recleaner concentrate contain 7%–9% Cu, 18% Cu, and 25% Cu, respectively. Recleaner concentrate also contains 2%–3% Mo.
