The production process of copper refined powder adopts three processes: crushing, grinding, and beneficiation. The selection of individual equipment and beneficiation process may vary slightly. During the crushing process, a three-stage closed circuit crushing is used, which can effectively complete the crushing and partial dissociation of the ore, thereby improving the subsequent grinding efficiency; During the grinding process, a two-stage and one closed grinding process is adopted, which can make the copper ore more fully ground; In the mineral processing process, the representative new technology that has emerged in recent years is mainly the mixed flotation process.

      The specific production process of copper concentrate is as follows: Copper ore beneficiation is the process of crushing and screening the ore obtained from mining to obtain high-grade copper concentrate, including steps such as crushing, flotation, separation, concentration, and dehydration. The ore undergoes tertiary crushing with a rotary crusher and a medium fine cone crusher, and then becomes fine particles. It is then ground into powder by a ball mill and enters the flotation cell. Reagents are added into the flotation cell. After continuous stirring by the flotation machine, the metal is adsorbed on the foam formed after stirring. The foam is suspended on the surface of the cell, and the copper concentrate powder flows into the cell on the side of the flotation cell with the foam for separation. The separated slurry is dehydrated by a combination of concentration and filtration, ultimately forming a copper concentrate. Through this process, The copper content can be increased from 0.5% to 30% of the original ore (smelting in a dry state involves smelting the copper concentrate into qualified anode copper, including pre drying, flash smelting, converter blowing, anode furnace refining, and anode casting processes. After pre drying, the moisture content of the ore decreases to below 13%; after drying, the moisture content of the ore decreases to below 3%. The product after smelting in a flash furnace is called "matte", which is liquid and has a copper content of 50% -75%, mixed with sulfur. The product of "matte copper" after converter blowing is "coarse copper", with a copper content of about 98.5%. The crude copper is refined in an anode furnace and cast in a disc casting machine to form anode copper.
