摘　　要：为了高效回收利用某铁品位45.20%、磁性铁含量32.40%的铜冶炼尾渣中的有价元素铁,同时减轻环境污染,提高资源利用率,在对该铜冶炼尾渣性质研究的基础上,进行了不同磨矿细度、弱磁选作业工艺参数等条件试验,并确定了最佳工艺参数。试验结果表明:在最佳工艺条件下,通过采用预选抛尾—磨矿(-0.045 mm95%)—单一弱磁选流程选别,可获得铁品位56.50%、铁回收率64.52%的铁精矿,实现了对该铜冶炼尾渣的回收利用,经济效益及环境效益显著。In order to efficiently recycle the valuable element iron in a copper smelting slag with iron grade of 45.20%and magnetic iron content of 32.40%,reduce environmental pollution and improve re⁃source utilization,based on the study of the properties of the copper smelting slag,the conditions of differ⁃ent grinding fineness and low intensity magnetic separation process parameters were tested,and the optimal process parameters were determined.The test results show that under the optimal process conditions,an iron concentrate with iron grade of 56.50%and iron recovery of 64.52%can be obtained by using a pre-se⁃lection tailings discarding-grinding(-0.045 mm 95%)-single low intensity magnetic separation process.The recovery and utilization of the copper smelting tailings are realized,and the economic and environmen⁃tal benefits are remarkable.
