摘要 赞比亚谦比希西矿体铜矿矿物种类多,Cu、Fe、S和Al2O3含量分别为1.69%、3.94%、1.61%和14.70%,属高铝复杂难选铜矿。为给该矿石浮选工艺确定提供依据,对西矿体矿石进行了浮选工艺研究。试验确定采用先选硫化铜矿再选氧化铜矿的优先浮选工艺流程。以水玻璃为矿浆分散剂、氧化钙为抑制剂、丁基黄药为捕收剂、2#油为起泡剂,进行硫化铜浮选,硫化铜浮选尾矿以硫化钠为活化剂、丁胺黑药+丁基黄药为混合捕收剂,进行氧化铜浮选,硫化铜与氧化铜浮选粗精矿混合后经3次精选,闭路试验可获得铜品位22.75%、铜回收率71.89%的浮选铜精矿,以及铜品位0.49%的浮选尾矿。

Abstract: The mineral types of west orebody copper ore from Chambishi mine are numerous,and the content of Cu,Fe,S and Al2O3 is 1.69%,3.94%,1.61% and 14.70%,respectively,which belongs to high aluminum complex refractory copper ore.In order to provide the basis for the flotation technology of the ore,flotation tests were conducted.A preferential flotation flow which copper sulphide ore was floated firstly followed by copper oxide ore flotation was used through flotation test.Sodium silicate,CaO,butyl xanthate and 2# oil was used as the dispersant,depressant,collector and frother,respectively,in copper sulfide flotation.Sodium sulfide and butyl xanthate combined with butylamine dithiophosphate was used as the activator and collector,respectively,to float the copper oxide from tailings of copper sulfide flotation.Then the mixture of the rough concentrate of the copper sulfide flotation and the copper oxide flotation was processed by three cleaning operations with closed flowsheet.The final concentrate was obtained with copper grade 22.75% and recovery 71.89%,and a tailings with copper grade 0.49%.
