Abstract

According to the properties of low grade phosphate rock, a positive-reverse flotation process is developed as a new way for making good use of phosphate rock and a good quantity of the product is obtained. In this paper the optimum flotation conditions with depressant dosage and collector dosage have been demonstrated. Na2SiO3 as depressant 3.2 kg/t and fatty acid as collector 0.44kg/t in the positive flotation, H3PO4 as depressant 4.4 kg/t and sodium oleate as collector 0.24kg/t in the reverse flotation, under this condition, we finally got the phosphate concentrate about the grade of P2O5 is 31.29%, the recovery is 59.17% and gained a better indicator of dressing.
