  新型环保铅抑制剂--ZJ201

  近日,紫金矿冶设计研究院(国重室)自主研发的ZJ201新型环保抑制剂在乌后紫金完成分离工业生产调试,再次通过生产实践验证,对铜铅混合精矿进行高效分选,为新型环保铅抑制剂的优化和推广应用奠定了坚实的基础。

  今年6月初,矿冶院新型环保铅开发利用课题组在乌后紫金开展三贵口铜铅分离工业生产调试,至今生产状况稳定。生产的铜精矿铜品位27.6%,含铅3.9%,含银1251.4g/t,金品位≥1g/t,铜作业回收率93.3%,铅损失率0.59%;生产的铅精矿铅品位65.1%,含铜0.19%,含银250.8g/t,铅作业回收率99.4%。对比三贵口铅锌矿2018年生产、销售铜铅混合精矿情况来看,使用新型抑制剂后可增加铜、金等金属销售收入,每年可产生经济效益超过2000万元。

  在此之前,矿冶院在元阳华西公司首次开展的抑制剂工业调试,铜精矿铜铅互含大幅度降低,铜、铅综合回收率分别提高6.7%、2.76%,特别是铜精矿中金品位从17g/t提高至100g/t以上。经济效益分析表明,使用新型药剂后的每吨原矿可增加效益约30元。

  ZJ201新型环保抑制剂采用可食用的高分子化合物为原料,药剂合成过程无三废产生。药剂成品无毒无味、绿色环保,消除了铜铅分离中常用的重铬酸钾、重铬酸钠、二氧化硫等有害药剂的危害,且ZJ201工艺流程适应性强,经多种矿石验证,均能得到较好的分离指标。

  近年来,矿冶院大力开展新型浮选药剂、烟气低温脱硝新药剂、类氰药剂和新型能源材料的自主研发工作,为集团公司的绿水青山贡献“紫金药剂”,为权属企业创造价值。目前,新型抑制剂、低温脱硝新药剂等获得技术突破,并在工业试验中取得显著经济效益和环保效益。
