The processing and production technology of copper ore mainly includes three processes: crushing, grinding and beneficiation. In the crushing process, the three-stage closed circuit crushing is a modern method suitable for the crushing of high hardness copper ore, which can complete the crushing and partial dissociation of the ore, thus improving the subsequent grinding efficiency. In the process of grinding, two-stage one-close grinding can make copper grinding more fully. In the beneficiation process, the most successful new process in recent years is the mixed flotation process.
