Yang Linlin such as the use of new processing equipment annular column flotation Experimental study of a sulfur iron ore, and the obtained concentrate grade 49.44%, 99.15% recovery good indicator confirmed annular than XFD flotation column flotation machine for sorting The advantages of this type of pyrite. Wu Huanxun introduced the ore dressing practice of fine-grained grade slurry of Yunfu Pyrite Mine. First, it uses separate flotation treatment. Second, it distributes three series of flotation treatments to the lean line, and improves the fine mud removal process in the front stage of flotation. The inflow of selected quantities has achieved certain results in reducing the grade of tailings in the overflow dressing. In order to further reduce the tailings grade of the overflow beneficiation and improve the recovery rate, a semi-industrial experimental study on the separation of pyrite vortex-static microbubble flotation column was carried out in cooperation with China University of Mining and Technology to explore the classification overflow of -3 mm pyrite. A new process for stream dressing treatment. Huang Gen et al. used two φ400 mm×4 000 mm cyclone-static microbubble flotation columns to make the slime on site in order to make efficient use of the slime produced during the production of a -3 mm product from a pyrite mine in Guangdong. 1 coarse 1 precision column flotation semi-industrial test. Firstly, the appropriate treatment volume, the chemical system, and the pressure of the circulatory pump in the flotation column were determined by the conditional test, and then the continuous operation was carried out for 72 h, and the sulfur grade of the sulfur concentrate was 48.46%, and the sulfur recovery rate was 93.71. Good indicator of %. Compared with the on-site selection of flotation machines, the sulfur recovery rate has increased by about 13 percentage points. Huo Tao et al. used a different flotation equipment to conduct a re-selection test on a pyrite flotation tailings. The results show that when the flotation machine is used, the coarse and fine two sweeping process can obtain the sulfur concentrate with the grade of 33.48% and the recovery rate of 65.28%. The closed-circuit test using a flotation column, a coarse and a fine sweep process, can obtain a sulfur concentrate with a grade of 32.84% and a recovery rate of 70.16%. Although the concentrate grade is slightly reduced, the recovery rate is increased by nearly 5 percentage points. . He Qingsong other analysis of Chongqing Nantong Coal Mining Company dry Bazi selected plant south of Sulfur Nantong Coal Preparation Plant processes and problems, propose using the new HQS heavy media cyclone - Small Diameter Dense Medium Cyclone - float The column-selective process is used to achieve efficient and efficient separation of coal-based pyrite, and the economic and technical feasibility of the process is discussed.

Pyrite ore dressing equipment
Flotation column is a kind of high-efficiency flotation equipment . Compared with trough flotation machine, it has the advantages of simple structure, small footprint, short manufacturing cycle and low energy consumption. In recent years, the application of flotation columns in pyrite ore dressing has increased.
