Abstract:There is a refractory copper-cobalt ore with high content of carbon and clay minerals in DRC. According to the ROM properties and benefication test results and the production practice of similar plant, the recommended test flowsheet was optimized. Design benefication process considered the processing of several different types of ore, such as upper oxidized ore, central mixed ore, deep primary sulfide ore, as well as the surface stockpiling oxidized ore, provides a reference for the development and utilization of domestic?and?international similar copper and cobalt ore due to the strong adaptability and operability.
