| titleOfInvention | A kind of beneficiation method of crystalline uranium ore |
| abstract | The invention belongs to the technical field of beneficiation, in particular to a beneficiation method for crystalline uranium ore. First, the ore is finely crushed, and the spiral chute is used for sorting to obtain the spiral chute gravity separation coarse concentrate and gravity separation tailings; the obtained spiral chute gravity separation coarse concentrate is ground with a rod mill to a fineness of less than 0.6mm, and the grinding The ore after mining is divided into 4 grades: ‑0.6～+0.4mm, ‑0.4～+0.20mm, ‑0.20～+0.074mm, ‑0.074mm; The 0.074mm particle size ore is separated and enriched by shaking table, and the gravity concentrate of each particle size is combined to obtain the shaking table gravity concentrate; the fine particle size less than 0.074mm is used to recover the crystalline uranium ore by flotation. . By adding ferric chloride and copper sulfate to activate the crystalline uranium ore, and using benzhydroxamic acid and sodium oleate as the crystalline uranium ore collector, the high-efficiency flotation of the crystalline uranium ore was realized. Through the combined use of gravity separation and flotation technology, the grade of uranium in the concentrate is greatly improved, and a high uranium recovery rate is ensured. |
