摘要
为合理高效利用袁家村闪石型原生磁铁矿石,在矿石性质研究的基础上进行了选矿工艺试验研究。试验结果表明:采用预先抛尾—再磨再选—浮选工艺流程处理该矿石,可获得铁品位为67.41%、铁回收率为62.81%的铁精矿,该工艺为袁家村闪石型原生磁铁矿石的合理开发利用提供了科学依据。
To reasonably utilize the original amphibole-type primary magnetite ore of Yuanjiacun,based on the study of ore properties,beneficiation process experiment was studied.Test results indicated that,the ore is treated by pre-tailing-re-grinding and re-sorting-flotation process and can obtain an iron concentrate having iron grade of 67.41%and recovery rate of 62.81%.The process provides a scientific basis for the development and utilization of the amphibole-type primary magnetite ore in Yuanjiacun.
