Forms of Titanium Occurrence in Bauxite

A comprehensive study of the distribution of titanium in lateritic-sedimentary bauxites from the Central deposit in Western Siberia, Sangaredi (West Africa), and in in situ bauxites from the Mainpat Plateau deposits in India has been conducted. It has been found that titanium in bauxites resents in the form of relict (anatase, titanomagnetite) and hypergenic (anatase, rutile) minerals, dispersed forms, as well as in the form of newly formed crystals (rutile). Each of these form exhibits specific morphological and geochemical characteristics. The distribution and forms of titanium occurrence in bauxites have a direct impact on the technological parameters of bauxite processing, which is crucial for optimizing of the enrichment processes aluminum ore.
