摘要: 河南某铁矿矿石中除磁铁矿外,还伴生有铜、硫矿物,其中硫矿物有相当一部分为磁黄铁矿。为了给该矿的矿床工业评价及矿石可选性评估提供依据,对该矿矿石进行了选矿试验研究。试验结果表明:采用铜、硫依次浮选—浮选尾矿弱磁选联合工艺流程,可以综合回收矿石中的铜、硫、铁。获得的铁精矿铁品位为65.10%,回收率为57.23%,硫精矿硫品位为42.00%,回收率为95.62%,铜精矿铜品位为19.20%,回收率为52.79%,并且铁精矿含铜和含硫分别为0.03%和0.25%,达到国家铁精矿粉矿二级品的含杂标准。

Abstract: A Henan magnetite ore contains also copper and sulfur minerals, with a considerable amount of sulfur minerals being pyrite. Test research was made on this ore for the industrial evaluation of the related deposit and the ore beneficiability. The results show that a combined process of sequential flotation of copper and sulfur and low intensity magnetic separation of flotation tailings can recover in a comprehensive way the copper, sulfur and iron from the ore, with the iron concentrate grading 65.10% at a recovery of 57.23%, sulfur concentrate grading 42.00% at a recovery of 95.62% and copper concentrate grading 19.20% at a recovery of 52.79%, The iron concentrate contains 0.03% copper and 0.25% sulfur, which satisfy the state standard for the impurity content in Class 2 iron powder concentrate.
