摘要
白云鄂博西矿区低品位铁矿石存在入选品位低、选矿利用成本高等问题,为合理利用该铁矿资源,在原矿矿石性质研究的基础上进行了选矿试验研究。结果表明,原矿采用干式磁选预先抛尾—高压辊磨—湿式磁选抛尾—湿式弱磁选工艺处理该矿石,可获得TFe品位66.09%、回收率63.25%、磁性铁回收率94.82%的合格铁精矿。试验结果为该低品位铁矿的高效开发利用提供参考依据。
There are a series of problems such as low grade and high cost of ore dressing and utilization of the raw ores in Bayan Obo West Mine.For the rational utilization of this iron ore resources,the ore dressing process was carried out on the basis of ore properties.The results show that the ore is treated with the raw ore dry magnetic pre-discarding tailings-high pressure roller mill-wet magnetic discarding tailings-wet weak magnetic separation process,and the qualified iron concentrate with the iron grade of 66.00%or more is obtained.The test results provide reference of the low grade iron ore efficient use.
