Carbothermal solid state reduction of manganese ore in hydrogen atmosphere. The aim of the project is to establish mechanisms of solid-state reduction of manganese ore by carbon in hydrogen and effects of gas atmosphere and other operation parameters on the reduction rate. The project will examine carbothermal reduction of manganese ore in hydrogen, helium and argon at different temperatures, ore compositions and sizes. The project's outcomes will be the reduction extent, rate and mechanisms. Th ....Carbothermal solid state reduction of manganese ore in hydrogen atmosphere. The aim of the project is to establish mechanisms of solid-state reduction of manganese ore by carbon in hydrogen and effects of gas atmosphere and other operation parameters on the reduction rate. The project will examine carbothermal reduction of manganese ore in hydrogen, helium and argon at different temperatures, ore compositions and sizes. The project's outcomes will be the reduction extent, rate and mechanisms. They will be used to assess the feasibility of solid-state reduction technology. This will be of importance to Australian manganese industry.Read moreRead less
Alternative technology for titanium tetrachloride: production and chlorination of titanium oxycarbonitride. The proposed project targets alternative cost-efficient technology for titanium tetrachloride, which is an intermediate product in production of titanium metal and titania pigment. More efficient technology for processing of titanium minerals will strengthen the position of Australia in the titanium industry at a global level. It has a potential to enhance Australia capacity to exploit nic ....Alternative technology for titanium tetrachloride: production and chlorination of titanium oxycarbonitride. The proposed project targets alternative cost-efficient technology for titanium tetrachloride, which is an intermediate product in production of titanium metal and titania pigment. More efficient technology for processing of titanium minerals will strengthen the position of Australia in the titanium industry at a global level. It has a potential to enhance Australia capacity to exploit niche markets for titanium dioxide white pigment and titanium metal, enabling Australia to capitalise on its huge mineral sands resource, rich in ilmenite and rutile. The project will also contribute to the theory of metallurgical processes, particularly to the gas-solid reactions in the reduction, carburisation, nitridation and chlorination processes.

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 oxycarbi ....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.Read moreRead less
Template-free Control of Titania Precipitation from Homogeneous Aqueous Solution. Used in the paint, plastic, ceramic, paper and synthetic fibre industries and having strategic nano-technological applications, titania is an important commodity for Australia, earning about $1.3 billion p.a. in exports. Better production methods through improved understanding of titania precipitation chemistry will help to increase our industrial productivity and minimise energy consumption. It may also lead to us ....Template-free Control of Titania Precipitation from Homogeneous Aqueous Solution. Used in the paint, plastic, ceramic, paper and synthetic fibre industries and having strategic nano-technological applications, titania is an important commodity for Australia, earning about $1.3 billion p.a. in exports. Better production methods through improved understanding of titania precipitation chemistry will help to increase our industrial productivity and minimise energy consumption. It may also lead to useful new processes and/or materials with catalytic properties. In an increasingly competitive global market, this is most relevant to Australian titania exporters and to Australian renewable energy programs (particularly for generating photovoltaic power).
