目前苏联选矿厂在分离铜钼混合精矿时,是在矿浆蒸吹条件下以Na_2S作为铜矿物和黄铁矿的主要抑制剂。当保证满意的分选指标时,抑制剂的用量很大是该方法的主要缺点,这与共很高的反应能力有关。此外,矿浆蒸吹使设备操作复杂化,并且也恶化了选矿厂的工作环境。使用不同种类的药剂抑制硫化铜矿物和黄铁矿,采用多种分离方案是国外铜钼混合精矿分离的特点。因此,最近八年间 At present, the Soviet Union concentrator in the separation of copper and molybdenum mixed concentrate, the slurry steaming under the conditions of Na_2S as a major inhibitor of copper minerals and pyrite. When a satisfactory sorting index is guaranteed, the large amount of inhibitor used is a major drawback of this method, which is related to the very high reactivity. In addition, slurry steaming complicates plant operation and also worsens the working environment of the concentrator. The use of different types of agents to inhibit copper sulfide minerals and pyrite, using a variety of separation programs is the separation of foreign copper and molybdenum concentrate characteristics. Therefore, the last eight years
