某地区低品位铁矿石选矿试验研究

摘要

Mineral processing experiments were conducted for a low⁃grade iron ore. Based on a trial test study, a combined flowsheet consisting of staged⁃grinding and staged magnetic separation combined with a flotation process with one roughing and one cleaning for desulfurization of iron concentrate from magnetic separation was adopted, resulted in the final iron concentrate with grade of 63.21% at a recovery of 63.53% with yield of 11.75%. The impurity content in the iron concentrate is lower than the commercial standards, also the iron concentrate with V2 O5 grade at 0.83% with a recovery over 80% showed a good enrichment of vanadium obtained.%对某低品位铁矿石进行了选矿试验研究。通过对矿样进行探索试验，最终以阶段磨矿阶段磁选⁃磁选铁精矿一粗一精浮选脱硫的联合流程，获得铁精矿产率11．75％、品位63．21％、回收率63．53％的指标。其杂质含量低于工业指标要求，并且矿物中V2 O5在铁精矿中有较好富集，品位为0．83％，回收率大于80％。
