甘肃某低品位难选钛铁矿磁电选矿试验研究

摘要

A system beneficiation study was carried out on a coarse ilmenite ore with TiO 2 13 .38%and TFe 21 .12%in Gansu province .The results showed that it was feasible for low grade refracto-ry ilmenite to be disposed by using combined flowsheet of gravity -magnetic-electrostatic separa-tion after grinding.And a separation indexes of ilmenite yield 13.35%, TiO2 45.97%, and ilmen-ite recovery 45 .46%were obtained .This study provided technical assistance for rational develop-ment of this type of ilmenite .%针对甘肃某含TiO213．38％、TFe 21．12％的钛铁矿，进行了系统选矿试验研究。试验结果表明，在磨矿条件下，采用重选—磁选—电选联合流程，可获得钛精矿产率13．35％、TiO2品位45．97％、回收率45．46％的较好试验指标。该试验研究为合理开发此类钛铁矿提供技术思路。
