Experimental Study on Flotation of Low Grade Phosphate Rock in Jianshan
In order to economically and rationally utilize low grade low phosphorus and high magnesium phosphate ores in Jianshan,the beneficia-bility and reagent system of the ores were studied by flotation experiments with high phosphorus and low magnesium.The test results show that:When low-grade phosphate ore and high-phosphorus and low-magnesium phosphate ore are 1:2,the grinding fineness of-0.074 mm rea-ches 92％,the dosage of sulfuric acid is 18.0 kg/t,the dosage of YP6 is 3.0 kg/t,and the dosage of phosphoric acid is 1.5 kg/t,The beneficia-tion indexes of P2O5 content of concentrate 29.84％,MgO 0.72％,Al2O3 0.82％,yield 75.95％,recovery 93.70％and P2O5 content of tailings 6.33％were obtained.
