新疆某铜铁矿综合回收试验

新疆且末某铜铁矿全铁品位为50.92%，铜品位为0.31%，含硫3.46%，为降低铁精矿硫品位及综合利用回收铜硫，对其进行了铁精矿脱硫及铜硫综合回收试验研究。通过工艺流程对比，确定采用组合药剂先浮选后磁选流程，最终获得了全铁品位为67.12%、铁回收率为76.39%、含硫为0.26%的铁精矿，硫品位为23.86%、硫回收率为79.28%的硫精矿，铜品位为15.74%、铜回收率为70.66%的铜精矿，铁精矿达到了质量要求，并实现了该类矿石的综合利用。

Comprehensive Recovery Test of a Copper-iron Ore from Xinjiang

A copper-iron ore from Xinjiang Qiemo with iron grade of 50.92%, copper grade of 0.31%, sulfur content of 3.46%, desulfurization of iron concentrate and comprehensive recovery of copper and sulfur test was conducted in order to reduce sulfur content in iron concentrate and comprehensive recovery and utilize of copper and sulfur. According to comparison of the separation process, iron concentrate with 67.12%iron grade, 76.39% iron recovery, 0.26% sulfur grade, sulfur concentrate with 23.86% sulfur grade, 79.28% sulfur recovery, copper concentrate with 15.74% copper grade, 70.66% copper recovery was achieved by chosing combination of medication and first flotation and then magnetic separation process. Iron concentrate could reach the quality requirements and comprehensive utilization of this type of ores was achieved.
