Abstract

Bauxites of Shevaroy hills were analysed for their mineralogical composition adopting X-ray and differential thermal analyses, heavy mineral and microscopic studies. Gibbsite and goethite are the ubiquitous and major constituents while boehmite, hematite, lepidocrocite, kaolinite, halloysite and quartz are present in minor amounts in certain samples only. There is a variation in the abundance of these minerals with the grain size of the bauxite. Magnetite, ilmenite, zircon, rutile and garnets are the heavy minerals present.
