| 摘 要： | 研究某难选铜硫矿石的浮选工艺，提高铜回收率。在原矿含铜1．09％，含硫32％的情况下，采用磨矿细度-74μm占70％，以ZH-01为捕收剂，用（石灰＋Na2S＋KG）组合抑制剂抑硫浮铜，经一粗二扫二精的工艺流程选别，获得铜品位14．2％，回收率70．30％。金品位3．7g／t，回收率33．5％，尾矿即为硫精矿的较佳指标。铜和金回收率分别比现生产工艺提高10％和11％。

| Abstract: | The floatation process for a refractory copper sulfur ore is investigated in order for improving the copper recovery. The excellent floating indexes are achieved with run-off-mine ore containing 1.09 % copper and 32 % sulfur by using of ZH-01 collector and combined depressor of lime, Na2S and KG. The grades of copper and gold in the copper concentrate are 14.2% and 3.7g/t, and the recovery are 70.30% and 33.5%, respectively, and the tailings are the sulfur concentrate. The recovery for the copper and gold are increased by 10% and 11% on the base of the spot production process. |
