Alternative processing of titanium minerals: carburisation and chlorination of rutile and ilmenite.

Australia produces about 40% of the world's stocks of ilmenite and 25% of rutile, which are used as raw materials for the titanium industry. Current methods for processing these minerals into pigment titanium dioxide and metallic titanium are complex, expensive and produce by-products that are environmentally dangerous. The project will study titania reduction from rutile and ilmenites to oxycarbides and reactions of chlorination of titanium oxycarbide. The aim is to establish fundamentals of titanium carburisation/chlorination processes and to assess their potential for processing of titanium minerals more efficiently. Outcomes will include reaction kinetics and mechanisms of reduction/carburisation and chlorination reactions, constraints and optimal conditions for carburisation/chlorination process.
