Problems solved by technology

[0009] However, such a beneficiation method requires coarse crushing and fine crushing before ball milling. After ball milling, the first roughing, the second roughing, the third roughing, and sweeping are carried out to obtain the concentrate , such beneficiation method is more complicated

Abstract

The invention relates to the field of beneficiation, in particular to a cellophane beneficiating method. The method comprises the following steps of: autogenously grinding raw cellophane; performing ball milling to obtain ore powder; and performing flotation on the ore powder by using a flotation column to obtain concentrate. The raw cellophane is autogenously ground into broken ore with the fineness of 45 to 50 percent, the broken ore is ball-milled into the ore powder with the fineness of 75 to 85 percent, the concentrate of which the MgO content is 0.8 to 0.9 mass percent is obtained by the flotation, the concentrate of which the recovery rate is 91.5 to 92.5 percent is obtained by the flotation through the flotation column, the concentrate obtained by the flotation is concentrated into concentrate pulp of which the water content is less than 40 percent, the concentrate pulp is filtered to obtain filter cakes of which the water content is less than 15 percent, and the obtained filter cakes are dried into concentrate powder of which the water content is less than 5 percent. By the cellophane beneficiating method, the beneficiating flow can be simplified.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a collophosite mineral processing method. Background technique [0002] At present, the world's phosphate rock resources have been gradually depleted, and phosphate rock resources are non-renewable. China's phosphate rock has been listed as one of the 20 kinds of minerals that cannot meet the needs of national economic development after 2010. Among the types of phosphate rocks in China, medium and low-grade phosphate rocks account for the vast majority, which are difficult to separate and treat, especially collophanite has more impurities, and the particles of collophanite are finer, so collophanite is more difficult to process. select. [0003] The prior art usually adopts a stirring type flotation machine for collophosite beneficiation, which specifically includes the following steps: [0004] Coarsely crush raw ore into coarse ore; [0005] Finely crushing the obtained coa...
