摘　　要：为高效回收利用某高铁硫精矿中的铜矿资源,在对某高铁硫精矿硫品位为18.53%、含铜0.724%的硫精矿进行矿石性质分析的基础上,进行了浮选工艺条件试验。研究结果表明:该高铁硫精矿在磨矿细度为-0.043 mm85%的条件下,以石灰为抑制剂,C330为捕收剂,经1粗6精开路浮选试验,可获得铜品位为16.90%、铜回收率为47.32%的铜精矿。In order to efficiently recycle the copper resources in a high-speed iron-sulfur concen⁃trate,the flotation process condition test was carried out based on the analysis of the ore properties of the sulfur concentrate with a sulfur grade of 18.53%and a copper content of 0.724%.The research results show that under the condition of grinding fineness of-0.043 mm accounting for 85%,with lime as inhibitor and C330 as collector,the copper concentrate with a copper grade of 16.90%and a copper recovery rate of 47.32%can be obtained after one roughing and six times of selective open-circuit flotation tests.
