Heavy medium cyclone separation process for phosphate rock

Heavy medium cyclone separation process is suitable for silicon-calcium phosphate mineral. Yichang Phosphate Mine is a marine chemical deposited phosphate rock deposit. The ore industry type is mainly siliceous calcium phosphate. The structure of the ore is mainly strip-shaped, the strip of phosphorus in the ore is wide, the hardness difference between the phosphorite and the gangue strip is large, the joint surface is not tight, and it is easy to dissociate. When the ore is broken to -15mm It can achieve more than 90% of the monomer dissociation of the phosphorite strip, which is suitable for heavy medium dressing . When the P 2 O 5 grade of the ore is 22.05% and the MgO content is 2.85%, the final phosphate concentrate P 2 O 5 grade is 28.06%, the MgO content is 1.67%, and the P 2 O 5 recovery rate is obtained by heavy medium. It is 87.64% and the yield is 68.82% of the ore dressing index. For example, the beating process of Huaguoshu Heavy Medium Plant is shown in Figure 1.
