Copper industrial minerals are: natural copper, chalcopyrite, chalcopyrite, beryllium copper, azurite, malachite and so on. More than 280 copper-bearing minerals have been discovered, with only 16 major. The main mining in China is chalcopyrite (copper with sulfur, iron compounds), followed by chalcopyrite and porphyrite.
Processing production process
The copper ore processing and production process mainly includes three processes of crushing, grinding and beneficiation. During the crushing process, the three-stage closed-circuit crushing is a modern high-hardness copper ore crushing, which can complete the ore crushing and partial dissociation work, thereby improving the subsequent grinding efficiency;
In the grinding process, the second-stage and one-close grinding is an efficient grinding process, which can make the copper ore grinding more fully. In the beneficiation process, the relatively successful new process that has emerged in recent years is representative of the mixed flotation process.
