Abstract: The main valuable minerals of a copper sulphide ore with high grade of native copper are native copper，chalcocite，chalcopyrite，pyrite，copper and cobalt sulfide and magnetite.According to the ore properties and the beneficiation tests from Australia，and in order to avoid the native copper with a good ductility from adhesion on the liners of the cone crusher and mill in dressing process to result in damage of the crusher and mill blockage，China Nerin Engineering Co.，Ltd.designs the targeted beneficiation process for the ore:In the crushing process，the roll crusher is used as the second and third crushing equipment，to make the native copper with size of greater than 40 mm be large flakes，and then separated from small one by sieving.The native copper ore in particle size of less than 40 mm after crushing are recovered by the process of the HPGR for comminution-drum washer+cylinder screen+vibrating screen for classification-jigging+spiral+table gravity separation.Then，through the process of grinding-flotation-low intensity magnetic separation，copper concentrate with Cu grade of 32% and Cu recovery of 95%,sulfur-cobalt concentrate with cobalt content of 1% and cobalt recovery of 65%，and iron concentrate with Fe grade of 68% and Fe recovery of 42% are achieved separately from the gravity tailings.This process design provides a new idea for efficient and rational development and utilization of the copper sulfide ore with high grade of native copper.
