摘　　要：对某地泥化的氧化铜矿进行了可选性试验研究。根据矿石的工艺矿物学特性,制定出"预先脱泥+Na2S诱导浮选"的工艺流程,有效避免了矿泥的不良影响,取得了较好的分选指标:铜精矿品位达21.14%,回收率达81.80%。A test is made for the beneficiability of some slimed oxidized copper ore. According to the mineralogical characteristic of the ore, a technological flowsheet of ＂pre-desliming ＋ Na2S induced flotation＂ is put forward, whereby the harmful effect of mud has been effectively avoided, obtaining better separating indexes such as copper concentrate grade of 21.14% and recovery of 81.80%.
