As one of the key minerals in mineral metals, mining of copper ore will undoubtedly contribute to the overall progress of society. Therefore, in this case, in order to effectively increase the copper metal recovery rate and significantly reduce the production cost, it is necessary to use a lower toxin beneficiation agent to avoid environmental pollution problems. At the same time, the process flow should be optimized. When selecting the main equipment, it must be based on the actual function of the copper ore beneficiation equipment and the actual situation of mineral exploitation in recent years. Try to use energy-saving and environmentally friendly new technology and new equipment to promote copper ore beneficiation. Efficient.
2 Beneficiation process and process
In the process of mineral processing, especially in the grinding process, we must adhere to the principle of “multiple crushing and less grindingâ€, and strive to make full use of new energy-saving technologies and green environmental protection in the process of copper ore beneficiation. New equipment. In general, when adopting new energy-saving and environmentally-friendly equipment, once the grinding operation is required, it is necessary to improve the equipment according to the actual conditions of the minerals, plan the crushing time and the grinding size in detail, and also correspondingly Adjust the grinding time, the grinding speed and the matching of the grinding medium. Try to use some new steel wire materials, lining materials and grinding aids. For example, mineral resources are mostly disseminated copper ore. Generally, three processes are used. One is the first rough selection, the other is two to three selections, and the last is one or two sweeps. [1]. If copper minerals have a finer particle size, then a phased grinding process can be considered. In the case of the treatment of the porphyrite, most of the coarse ore concentrates are used for re-grinding, that is, a rough grinding, rough selection, and sweeping, and then re-grinding and re-selecting the coarse concentrate after the grinding process. The copper concentrate and sulfur gold ore thus obtained will be of higher quality. In general, the larger the number density of copper ore mostly pyrite and chalcopyrite, pyrite but if one has a high content, then the sorting will be faced with difficult problems. In order to obtain both the sulfur concentrate and the copper concentrate at the time of sorting, a second sorting must be carried out.
3 Copper mine equipment selection principle
First, when selecting equipment, it needs to meet the plant scale, equipment form, ore properties and process requirements. Second, try to choose some reliable technology with high quality and energy-saving and environmental protection characteristics, as well as new equipment that the country has identified. After fully considering the price and performance of the equipment, the same equipment can be selected [2]. Third, some national styling products with simple maintenance, safety and reliability, and convenient operation are also the main targets for copper mine equipment selection. Fourth, in the process of copper ore equipment selection, it is necessary to fully consider the fluctuation of the processing volume caused by the change of ore properties. Fifth, the selected copper ore equipment must have the characteristics of convenient supply and reliable source.
