针对某含砷黝铜矿和硫砷铜矿的难选铜矿的矿石性质，为得到砷含量合格的铜精矿，采用分步浮选的工艺流程，即先选用对黄铜矿选择性好的捕收剂Z‐200回收以黄铜矿为主的铜矿物，再以丁黄药和PQ为捕收剂回收以砷黝铜矿和硫砷铜矿为主的含砷铜矿物．对铜品位0．65％的原矿，获得两个含砷不同的铜精矿产品，铜品位22．44％、回收率36．48％的铜精矿1，铜品位18．45％、回收率46．45％的铜精矿2，总铜回收率为82．93％．其中铜精矿1含砷0．28％，铜精矿2含砷1．35％，铜精矿1达到了一级品铜精矿的含砷要求．

To get copper concentrate qualified at arsenic content ,branch flotation technology was applied in mineral processing of a refractory copper ore including tennantite and enargite .The first step was to recy‐cle the low arsenic copper mainly existing in the form of chalcopyrite with collector Z‐200 of good selectivi‐ty ,and then butyl xanthate and PQ were used as collector to recycle the arsenic copper mainly consisting of enargite and tennantite .Two copper concentrate products differing in arsenic content were obtained from crude ore with the Cu grade of 0 .65% :copper concentrate 1 (Cu grade 22 .44% ,recovery of Cu 36 .47% );copper concentrate 2 (Cu grade 18 .45% ,recovery of Cu 46 .45% ) .The total recovery of Cu was 82 .93% . Arsenic content was 0 .28% in copper concentrate1 and 1 .35% in copper concentrate 2 .The latter is with‐in the arsenic content range of the first‐class copper concentrate .
