Belongs to the Hunan Nonferrous Metal Technology Institute staff have done a lot of long-term experimental study beneficiation in this area, through the tireless efforts of the Task Force research team, continuous technical innovation and technical research, completed a series of experimental research, we have achieved a major technological breakthrough. Pioneering the introduction of magnetic separation process into copper oxide ore beneficiation, and combining hydrometallurgy with flocculation technology and magnetic separation technology to make the two processes play a synergistic effect. For the guidance, under the premise of ensuring the recovery rate, the copper and cobalt concentrate grades are maximized, and the concentrates which are suitable for modern metallurgical processes are produced, and the copper recovery rate exceeds 90%. At the same time, it also solves the filtering problem caused by the slime. The process can remove the alkaline substances in the concentrate, which will greatly reduce the acid consumption of the wet smelting, thereby greatly reducing the operating cost of the wet smelting. This innovative process is also widely used for the copper oxide and cobalt mines in Katanga and other minerals. At the same time, the process has broad adaptability to changes in ore properties.
