Occurrence State of Iron and Titanium in Kaolinite

Abstract

The process mineralogy characteristics, such as chemical composition, mineral components and contents, the occurrence of the main mineral, the occurrence state of Ti and Fe, and the mineralogy factors affecting beneficiation indexes, were studied in detail with the methods of lens-below identification, scanning electron microscope, chemical elements analyses, and the chemical phase analyses. The results show that kaolinite mainly distributed in villform and hexagonal flake form, little distributed in tube form. The aggregate of kaolinite irregularly distributed, always in floc, rodlike and wormlike form. Hematite, limonite, anatase, and fine grain- sized detrital quartz were mingled in intergranular spaces, with the average content of Fe at 0.24%, TiO2 at 0.03%. The iron and Titanium were mainly distributed in hematite and anatase form in the ores, these two minerals could both be removed with beneficiation method, and the application value of kaolinite would be improved.
