In short, the ore beneficiation process is quite complicated. Common physical beneficiation methods have magnetic separation, gravity separation process, the commonly used chemical method are flotation process and reverse flotation. Reasonable beneficiation methods can improve the beneficiation indicators.

Appropriate improvements through the use of new energy efficient equipment on the comminution process: determining reasonable crushing, grinding size to adjust crushing time, mill speed, and the ratio of grinding media, the use of new materials steel ball, linings, research and application of grinding aids. Combined ore characteristics, to optimize the comminution process structure, the implementation stage grinding mill and separation, improve the pass rate of comminution product size, to achieve the purpose of reducing energy consumption. Further strengthen the process mineralogy research and has played an important role in raising the level of beneficiation technology.

Further,most of the ore associated metal component can impact the smelting of the main metals, and make the metal smelting process complicated, for example,harmful zinc in the copper-lead ores, but the ore of main zinc ores can be impacted negative effects, mixture sulfur and phosphorus in the iron ore are greatly not conducive to the process efficiency. Furthermore, some of the variety of mining substances ore needs refining processing in turn, some elements of which are useful.

Although copper flotation technology is more traditional and mature, but the research work carried out more active. Specific performance: Mineral processing equipment is large, and strive to energy saving; further reduce copper ore grade, improve resource utilization; improve copper and associated metal recoveries and reduce production costs; efficiency and low toxicity pharmaceutical processing, reduce environmental pollution; optimization process and other.Copper ore beneficiation production line is usually based on the principle of 'more crushing and less grinding', develop and have first choice of energy efficient copper ore beneficiation equipment.
