摘　　要：针对国外某钛铁矿矿物组成复杂,有价矿物之间共生关系密切,且钛铁矿嵌布粒度细等问题,采用阶段磨矿—阶段选别的磁选—浮选工艺流程对该难选钛铁矿矿石进行了选矿工艺试验研究。结果表明,对含TFe 55.36%、TiO_(2)9.91%的原矿,采用该工艺后,可获得TFe品位64.50%,回收率81.70%的铁精矿和TiO_(2)品位为47.22%、回收率为50.55%的钛精矿。该工艺为开发利用该矿产资源提供了技术支撑。In view of the complex mineral composition of a ilmenite from overseas,the close symbiotic relationship between valuable minerals and the fine particle size of ilmenite,the experimental study on the beneficiation process of the refractory ilmenite ore was carried out using the stage grinding-stage separation magnetic separation-flotation process flow.The results show that the iron concentrate with TFe grade of 64.50%and recovery rate of 81.70%,the titanium concentrate with TiO_(2)grade of 47.22%and recovery rate of 50.55%can be obtained from the run-of-mine with TFe grade of 55.36%and TiO_(2)grade of 9.91%.This process provides a technical support for the open utilization of the mineral resources.
