| 摘 要： | 云南某铁矿铁平均品位为38.1%,主要以赤铁矿和褐铁矿形式存在,有害元素硫、砷的含量极低,砷含量为0.002%,硫含量为0.01%,对矿石的利用不造成影响。矿石中磷含量高,磷平均含量为0.44%对矿石的影响较大。采用强磁选和重选方法对矿石进行了研究,探索一个合理可行的流程,在提高铁的品位和回收率的基础上降低磷和硅的含量。

| Abstract: | The average iron grade of an iron ore in Yunnan is 38.1%,mainly occurring in the form of hematite and limonite with very low content of harmful elements sulfur(0.002%) and arsenic(0.01%),which has no impact on the utilization of the ore.The phosphorus content in the ore is high with average content of 0.44% with relatively large influence on the ore.High-intensity magnetic separation and gravity separation are adopted to study the ore and a feasible process is explored,which can improve the grade and recovery of iron and reduce the content of silicon and phosphorus as well. |
