Current Status of Ilmenite Beneficiation Technology
Titanium and iron are closely related in nature although titanium is the ninth most abundant element in the Earth s crust. Iron in titanium ores must be removed for use as feedstocks in the manufacture of titanium dioxide pigments and pure TiCl4 for metal titanium. In this study various beneficiation processes of ilmenite for production of TiO2 have been reviewed and compared.

A Study on the Roasting Process for Efficient Selective
· We investigated the effects of ilmenite roasting temperature on the efficiency of iron oxide removal from the obtained residue by selective chlorination. Roastinginduced phase transformations were analyzed by xray diffraction measurements and the phase composition of roasted residue was shown to be determined by process conditions. The highest iron oxide removal efficiency was

The Upgrading of Ha Tinh Ilmenite to Synthetic Rutile by
Becher process was applied for upgrading Ha Tinh ilmenite concentrate (5455 TiO2) to synthetic rutile. The process includes reduction of ilmenite concentrate using anthracite coal as reductant followed by aeration of reduced ilmenite in ammonium chloride solution (NH4Cl). The controlled parameters were temperature and NH4Cl concentration.
