| Abstract: |
| In order to obtain qualified phosphorus concentrate, the de-flotation test was carried out on the ore by using the dephosphorization collector BK425 and the dealant HA-1. The flocculation test was carried out on the refractory phosphate rock. The When the fineness of the ore grinding is -0.074mm 70%, after the anti-flotation de-magnesium (a rough sweep) - anti-flotation de-aluminum (a rough two fine) full open process, you can get P2O5 grade 31.14% Al2O3 content of 2.60%, MgO content of 0.92%, P2O5 recovery of 79.54% of the phosphorus concentrate. |
