| 摘 要： | 在某硫化铜矿浮选过程中,进行了酯类捕收剂PZA与丁基黄药、丁基铵黑药、Z200等对比研究,发现PZA对铜、银具有良好的选择性,与丁基黄药组合效果更佳。原矿铜、银品位分别为0.28%和8.50g/t情况下,采用铜硫混合浮选—铜硫分离工艺流程,最终获得了铜精矿Cu品位21.58%、回收率83.94%,Ag品位500.10g/t、回收率62.99%的技术指标,较好的实现了银在铜精矿的定向富集。

| Abstract: | In the flotation process of a copper sulfide deposit, the ester collector PZA was compared with butyl xanthate, ammonium dibutyl dithiophosphate and Z200. It was found that PZA had good selectivity for copper and silver, and the combination effect with butyl xanthate was better. Under the condition that the grade of raw copper and silver is 0.28% and 8.50g/t respectively, the technical indexes of Cu grade 21.58%, recovery 83.94%, Ag grade 500.10g/t and recovery 62.99% of copper concentrate. Meanwhile, the directional enrichment of silver in copper concentrate is realized. |
