| Abstract: |
| In order to improve the flotation separation indexes of some molybdenum-copper sulfide ore associated with tungsten in Guangdong, reasonable reagent system and beneficiation processes were conducted. Strengthening take-off reagent before the separation of mixed concentrate, using JBS as the collector of molybdenum, and adopting DSY conducting selective depression for chalcopyrite, the separation effect of Mo-Cu can be significantly improved. And the better test indexes can be obtained: the molybdenum concentrate assaying 49.25% Mo at the recovery of 91.50%; and the copper concentrate containing 21.45% Cu with the recovery of 99.96%. |
