某铜硫铁矿含铜0.53%,硫4.78%,铁21.15%。在工艺矿物学的基础上,试验探索出适合该矿石的工艺条件,采用“优先浮选-铜尾活化选硫-尾矿磁选富集-反浮选选铁”流程进行试验。最终依次获得含铜22.23%、回收率为94.59%的铜精矿,含硫32.43%、回收率为60.51%硫精矿,含铁68.84%、回收率为44.75%的铁精矿,选别效果较好。 A copper pyrite containing 0.53% copper, sulfur 4.78%, iron 21.15%. On the basis of technological mineralogy, the process conditions for the ore were explored and tested by using the process of “preferential flotation - copper tail activation sulfur - tailings magnetic separation - reverse flotation election”. Finally, copper concentrate with 22.23% copper and 94.59% recovery rate was obtained in turn, with 32.43% sulfur and 60.51% sulfur concentrate, 68.84% iron and 44.75% recovery. better.
