Development direction of mine mineral processing technology in China

Beneficiation process technology and quality iron ore concentrate part of our country has reached the international advanced level, but China's iron ore poor, miscellaneous, small and variety of features, the steel industry to the new requirements of iron ore and other mineral processing workers to our proposed new challenge.

Therefore, China's metallurgical mining mineral processing technology as well as a deeper development:

1) While promoting the application of high-quality iron concentrate beneficiation technology represented by magnetic separation-reverse flotation, high-efficiency magnetic separation (magnetic re-election), etc., the beneficiation process should be as efficient and simple as possible, so it should be strengthened. Research on mineral processing equipment and mineral processing technology to achieve the best results in the most appropriate process. The reverse flotation process has important application prospects for improving the recovery rate of metals, and research on reverse flotation reagents should be actively strengthened.

2) While continuing to pay attention to the technology of iron concentrate and iron reduction in iron concentrates, we should pay attention to the research of other harmful impurities technologies, including S, P, K, Na, F, etc. in the future.

3) The research on the beneficiation technology of inlaid granular ultrafine iron ore and composite polymetallic red iron ore should be further strengthened to further improve the utilization rate of lean red iron ore in China.

4) In terms of grinding and sorting equipment, we should focus on the introduction and cooperative development of energy-saving superfine crushing equipment in the future. We should increase the introduction and digestion of foreign advanced technology and equipment, and improve the overall technical and equipment level of China's iron ore as soon as possible. At the same time, we will consider the development and research work of the coarse-grain tailing process and related equipment. The development of energy-saving beneficiation equipment capable of effectively recovering fine-grained iron minerals should be further strengthened, including permanent magnetization of strong magnetic equipment, fine-grain flotation machine and flotation column. More in-depth study of multi-cylinder magnetic separators with multi-segment selection performance.

5) In terms of mineral processing reagents, we should focus on the development of various ore adaptable, high efficiency, low temperature, non-toxic agents on; The study also formulated, while adding the pharmaceutical compound; the focus should now be able to develop non-quartz flotation High-efficiency collector for silicate-based gangue minerals and application range for expanding reverse flotation process.

6) The current research on flotation equipment is mainly to the direction of large-scale and energy-saving, the lower limit of flotation particle size is reduced, and the composite force field is introduced into the flotation machine. In addition, the automatic control of flotation machine should also be strengthened. . There is still a lot of work to be done on the application of flotation columns in iron ore mines, which has great prospects.

7) In the filtration and dewatering equipment : 1 research and development of high-efficiency filter media; 2 development of multi-functional integrated components to enhance sealing; 3 development of composite filtration technology equipment; 4 equipment large-scale, energy-saving and automation.
