Abstract: The process research on the recovery of copper and zinc of a sulphide ore in Ganzhou Jiangxi province was briefly introduced. When the flowsheet of speed flotation for part of copper, regrinding and cleaning for rough copper concentrate and recovering zinc from copper tailings by flotation was adopted for the ore. Finally, the copper concentrateⅠ containing copper30.55% and zinc3.91% and the copper concentrateⅡ containing copper26.11% and zinc4.99% were obtained. The comprehensive recovery of copper reached 90.8%. The zinc concentrate containing zinc45.20% and copper2.97% was obtained with the the recovery of zinc as 81.57%. Therefore, the aim of the separation of copper and zinc was reached.
