AN IMPROVED PROCESS FOR PRODUCTION OF HIGH GRADE SYNTHETIC RUTILE FROM TITANIFERROUS ORES

摘要

This invention relates to improvements in beneficiation of low grade ilmenite to produce valuable compounds such as high grade synthetic rutile or beneficiated ilmenite. The invention is more particularly related to improved process for removing iron and other acid soluble constituents including Uranium & Thorrium, from titaniferous ore, particularly "OR" Ilmenite (An Indian Ore), containing low percentage Titanium Oxide, This product Synthetic Rutile, containing (95 ± 1%) Titanium Oxide and impurities such as iron, vanadium, manganese, chromium, uranium & thorium, below objectionable level, can be used as pigment. Also due to its encouraging particle size, it can be marketed as feed materials for chlorination process.[IN-CHE-2010-00782A]
