BENEFICIATION OF TITANIUM BEARING MATERIALS

摘要

This invention relates to the beneficiation of titanium bearing materials having a substantial component of anatase and/or rutile and/or pseudorutile structure. Such materials include anatase ores and minerals and other sources of anatase, as well as blends or mixtures that include traditional sources of titanium and titanium dioxide such as ilmenite and titanium slag. The invention is of particular, though not exclusive, interest in the processing of anatase materials to titanium dioxide of pigment quality. The process is additionally effective in processing materials having a substantial component of anatase or rutile, e.g. leucoxene.
