Abstract

Ilmenite from the beach and dune environments of the Visakhapatnam-Bhimunipatnam placer sand deposit has less TiO₂ and more total iron contents, as compared to its stoichiometric composition. Its trace elemental concentrations indicate its basic percentage. It has exsolution features and four types of intergrowths, viz. ilmenite-Hematite, hematite-Ilmenite, graphic intergrowth and ilmenite-Rutile. Hematite phase in ilmenite incorporate excess iron in the structure of ilmenite. Based on the geochemical and ore mineralogical aspects, ilmenite of present study area is more suitable for pigment-Manufacturing than to synthetic rutile preparation.
