摘要/Abstract

摘要： 广西某铜矿石铜氧化率在27%以上，且含1%左右的碳质，属难选半氧化铜矿石。矿山选矿厂采用直接常温浮选工艺处理该矿石，铜精矿品位只有18%左右且回收率不到60%。为了给现场工艺流程改造提供依据，以硫化钠为硫化剂、丁黄药+DY组合为捕收剂，在60 ℃下对该矿石进行了预脱碳加温硫化浮选试验，获得了Cu品位为20.57%、Cu回收率为62.75%的铜精矿，与现场生产相比，选别指标得到了显著提高。

Abstract: A certain copper ore in Guangxi has the copper oxidation rate of more than 27%, and contains about 1% of the carbonaceous matter.It belongs to the refractory semi-oxidized copper ore.The direct flotation process at room temperature was selected to handle this kind of ore by the concentrator, and copper concentrate with the copper grade of only about 18% and recovery of less than 60% was obtained.In order to provide the basis for transformation of the on-site process, and taking sodium sulfide as vulcanizing agent and the combination of butyl xanthate + DY as collector, experiments of the preliminary decarburization and heat vulcanization process at 60 ℃ were carried out, obtaining copper concentrate grading at 20.57% with Cu recovery of 62.75%.Compared with the on-site production, the beneficiation indicators have been significantly improved.
