摘　　要：利用矿物定量解离系统(MLA)对云南某钛选矿厂尾矿进行了工艺矿物学研究,查清了矿石的矿物组成和目的元素的赋存状态,着重研究了目的矿物的共生关系、粒度分布特征、解离度特征等工艺性质。尾矿中金属矿物主要为钛铁矿、磁铁矿、赤褐铁矿;脉石矿物主要为高岭土、石英、铁辉石、钾长石、黑云母、锰辉石等。最后阐述了影响尾矿中钛铁矿选别的矿物学因素。The process mineralogy study was carried out for tailings of one Yunnan titanium dressing plant by using of mineral liberation analysis system （MLA）, the mineral composition and the occurrence state of destination element was checked out, the symbiotic relationship, particle size liberation degree, the features of liberation degree and the other process characteristics is mainly studied. The metal minerals in railings mainly are ihnenite, magnetite, hematite and lilnonitel ; The gangue minerals mainly are ： Kaoline, quartz, ferrosilite, potash feldspar, biotite, manganese pyroxene and so on. Finally, the mineralogical factors that affect ihnenite selection from railings are stated.
