摘要

摘要: 针对攀西某选铁尾矿进行了钛铁矿浮选药剂优化试验研究，其TiO₂品位为16.6%，主要矿物为钛铁矿、钛磁铁矿、辉石、橄榄石，次要矿物为斜长石、绿泥石。经过捕收剂、抑制剂、硫酸等药剂优化试验，利用硫酸+EMA+MOH，通过磁选除铁-浮选脱硫+一粗一扫五次精选选钛流程，闭路试验可以获得钛精矿产率25.18%，TiO₂品位46.48%，回收率71.31%的良好指标，为攀西矿区选铁尾矿中钛铁矿的回收提供技术参考。

Abstract: In this paper, the optimization test of ilmenite flotation reagents was carried out for an iron dressing tailing in Panxi. With a TiO₂ grade of 16.6%, this tailing is mainly composed of ilmenite, titanomagnetite, pyroxene and olivine, and the secondary minerals are plagioclase and chlorite. The types and dosages of collectors, inhibitors and sulfuric acid were optimized. Using the combination of sulfuric acid, EMA and MOH, a five-time titanium concentration process was obtained, including iron removal by magnetic separation, flotation desulfurization, one rough selection and one sweep selection. Under the optimal conditions, a good index of titanium concentrate yield of 25.18%, TiO₂ grade of 46.48% and recovery of 71.31% can be obtained in the closed circuit test, which provides a technical reference for the recovery of ilmenite from iron separation tailings in Panxi mining area.
