摘要
针对山东某低品位铁矿石进行了可选性试验研究,确定了采用预先磁选抛尾、一段磨矿粗选、粗选精矿再磨再选提高精矿全铁品位的工艺流程,最终获得铁精矿产率28.16%、全铁品位65.84%、全铁回收率74.64%的选别指标,该研究结果为该矿石的可选性评价提供了重要的技术依据。
An optional experimental study was carried out on a low-grade iron ore in Shandong,and the process of using pre-magnetic separation tailing,one-stage grinding rough selection,rough selection of concentrate re-grinding and re-election to improve the whole iron grade of concentrate was determined.The selection index of iron concentrate yield 28.16%,total iron grade 65.84%,and total iron recovery rate 74.64%was obtained.The research results provided an important technical basis for the optional evaluation of the ore.
