我矿矿床系一层控碳酸型铅锌矿床。目前,选矿厂采用优先选铅的浮选流程,生产铅精矿、锌精矿和混合精矿三种产品。自投产以来,浮选药剂单耗较高,1981年全厂铅锌浮选总药剂单耗为1309(克/吨),其中锌浮选硫酸铜用量为915(克/吨),占总药剂单耗69.90％。全年硫酸铜费用占总药剂费用的62.39％。硫酸铜过量易引起黄药的损失,造成选矿药剂成本的增高,同时加重了污染。1981年锌精矿的硫酸铜费用为15.03(元/吨)。因此,减少总药剂单耗,
My ore deposit is a layer of carbonate-type lead-zinc deposits. At present, the beneficiation plant adopts the preferential lead selection flotation process to produce three products of lead concentrate, zinc concentrate and mixed concentrate. Since put into production, the unit consumption of flotation reagents is relatively high. In 1981, the total unit consumption of lead-zinc flotation was 1309 g / t, of which, the amount of zinc sulfate flotation was 915 g / t, Unit consumption of 69.90%. The annual cost of copper sulfate accounts for 62.39% of the total drug costs. Overdose of copper sulfate can easily lead to the loss of xanthate, resulting in the increase of the cost of beneficiation chemicals and aggravating the pollution. In 1981, the cost of copper sulfate in zinc concentrates was 15.03 yuan / ton. Therefore, to reduce the total drug unit consumption,
