攀西微细粒钛铁矿工艺矿物学特征

以传统工艺矿物学研究方法为基础，结合化学分析、XRD，SEM及MLA等手段，对微细粒钛铁矿物料的化学组成、矿物组成、粒度分布、矿物嵌布特征进行了研究，在此基础上，对物料分选特性进行了讨论分析.研究结果表明:物料中67.04%的有价元素Ti赋存在钛铁矿中，脉石矿物主要为钛辉石、绿泥石和长石;物料中-19μm粒级产率达74.33%，其中各矿物粒度分布差别较大，有用矿物粒度较脉石矿物细;钛铁矿矿物单体解离度为90.43%，与钛辉石紧密连生.该研究结果为攀西微细粒钛铁矿物料的高效回收提供了依据.

Mineralogy Features of Micro-fine Ilmenite in Panxi Region

Based on the typical process mineralogy method， the chemical composition， mineral composition， size distribution and dissemination characteristics of the micro-fine ilmenite sample were investigated through chemical analysis， XRD，SEM and MLA， and then the sample separation features were analyzed and discussed. The research showed that the valuable element Ti of 67.04% occurs in the form of ilmenite， and the primary gangue minerals are titanaugite， chlorite and feldspar. Particle size below 19μm reaches 74.33% in the sample， among which the size distribution of each mineral has a significant difference， and the valuable minerals are finer than that of the gangue minerals. The ilmenite liberation degree is 90.43%， which is closely interlocked with titanaugite. The results provide the basis for the high-efficiency recovery of the micro-fine ilmenite.
