| Abstract: |
| In this article, the positive flotation test study on the lead-silver flotation tailings of some hard-rock uranium mine with grinding fineness of -0.074mm content 50% was carried out. The U grade of the lead-silver flotation tailings is 377g.t-1, and the main uranium-bearing mineral is mendeleevite. Uranium concentrates with U grade of 5465 g.t-1, CeO2 grade of 5406 g.t-1, U recovery of 89.04%, CeO2 recovery of 69.29% can be obtained by two-roughing, two-cleaning and one-scavenging closed- circuit test. The enrichment ratio of uranium concentrates is 14-15 times, and 87.67% of calcium-bearing minerals are removed. |
