In order to improve the effect of iron ore grinding process, researchers are pay attention to the grinding machine performance, flotation standard. 

Mineral process chemical agentbeneficiation reagent plays an important role in the mineral processing plant, the beneficiation effect varies with the performance of beneficiation reagents. The most used reagents are capture agent and inhibitor, in which, the capture agent accounts for the beneficiation effect in a big part, it mainly divides into xanthate type, mercaptan type, sulfur-nitrogen type, and sulfur ammonia type. according to the process technology, the used reagent shall be changed as followed.

The main purpose of non-ferrous metal beneficiation is to separate useful minerals and gangue minerals, and directly remove harmful substances from mineral resources, thereby providing more high-quality mineral energy for the industrial sector.
