  针对传统重铬酸钾、氰化钠铜铅分离抑制剂的剧毒问题,设计合成出新型环保方铅矿抑制剂ZJ201,建立年产达1000t该抑制剂的工业生产线,已申请国家发明专利1项。2019年6月在乌拉特后旗紫金矿业有限公司实现铜铅分离工业化应用,实现了从含铜1.5%~3.0%的铅精矿中环保高效回收铜技术,得到铜精矿铜品位>28%,铜回收率>93%的良好指标,年新增效益约2000万元。

  在元阳华西的780硐多金属矿属难分选矿石,原工艺采用“CMC+亚硫酸钠+水玻璃+腐殖酸钠”作为方铅矿抑制剂,铜铅无法有效分离,得到的铜精矿铜品位15.93%,含金33.56g/t,铜回收率48.76%。采用ZJ201对该矿石进行铜铅分离,生产应用可得到铜精矿铜品位23.41%,,含金100.32g/t,铜回收率70.43%,并得到合格的铅精矿。相比原工艺有效降低产品铜铅互含,大幅提高铜精矿中的铜、金品位和铜回收率,可增加产值约87元/(吨•原矿)。
