Although some of China's iron ore beneficiation equipment and concentrate quality have reached a certain level, the new requirements of the steel industry for iron concentrate have posed new challenges to China's beneficiation equipment industry due to the characteristics of poor, mixed, fine, and diverse types of iron ore. Therefore, China's metallurgical mining beneficiation technology still has deeper development:
(1) While continuing to pay attention to the technology of extracting iron and reducing silicon from iron concentrate, research on reducing other harmful impurities, including S, P, K, Na, F, should also be emphasized in the future.
(2) Further research should be conducted on the beneficiation technology of ultrafine grained hematite and composite polymetallic hematite, in order to improve the utilization rate of China's lean hematite.
(3) In terms of mineral processing reagents, emphasis should be placed on developing reagents that are highly adaptable to various ores, resistant to low temperatures, and non-toxic; Study the simultaneous formulation and addition of compound drugs; At present, the focus should be on developing collectors capable of flotation of non quartz silicate gangue minerals and expanding the application scope of reverse flotation technology.
(4) In terms of filtration and dehydration equipment: ① Research and development of filtration media; ② Develop multifunctional integrated components to enhance sealing performance; ③ Developing composite filtration technology equipment; ④ Large scale, energy-saving, and automated equipment.
(5) At present, research on flotation and beneficiation equipment is mainly developing towards large-scale and energy-saving directions. The limitations of flotation and beneficiation equipment have been reduced, and composite force fields have been introduced into flotation machines. In addition, research on automatic control of flotation machines should also be strengthened. There is still a lot of work to be done for the application of flotation columns in iron ore beneficiation equipment, which has great prospects.
(6) While promoting the application of high-quality iron concentrate beneficiation equipment represented by magnetic separation reverse flotation and magnetic separation (magnetic reselection), the beneficiation process should be as simple and straightforward as possible. Therefore, research on beneficiation equipment and processes should be strengthened to achieve optimal results through appropriate processes. 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.
(7) In terms of grinding and sorting equipment, we should focus on the introduction and cooperative development of energy-saving ultrafine crushing equipment in the future. We should increase the introduction and digestion of foreign technology and equipment, and improve the overall technical equipment level of China's iron ore as soon as possible. Simultaneously considering the development and research of coarse-grained tail throwing technology and related equipment. Further efforts should be made to strengthen the development of energy-saving beneficiation equipment that can effectively recover fine iron minerals, including permanent magnetization of strong magnetic equipment, fine particle flotation machines, and flotation columns. We need to conduct more in-depth research on multi tube magnetic separators with multi-stage continuous selection performance.
