一水硬铝石型高钛铝土矿中钛的赋存状态研究
Research on the Form of Occurrence of Itanium in Diasporic Bauxite with High Tannium
摘要
Abstract
In this paper,the conventional chemical analysis method,XRD,polarizing microscope,scanning electron microscopy(SEM) and other modem advanced analytical instrumentation are used for the the chemical composition research,phase composition and microstructure morphology of Yunnan diasporic high titanium bauxite.At the same time,the occurrence state of titanium is analyzed by scanning electron microscope (SEM) element distribution graph.Results indicate that the ore belongs to bauxite of high titanium and high A/S.In the ore,the content of TiO2,Al2O3,and SiO2 is respectivly 8.23％,58.02％ and 6.69％,and A/S is 8.68.Beyond that,the ore contains a certain amount of iron.The content of Fe2O3is 14.51％.Ti-containing mineral in the ore is mainly the form of anatase,followed by a certain amount of ilmenite and a small amount of plate titanium ore,and they are embedded in the substrate of ore in the form of regular or irregular clumps or inclusions.关键词
