Uses of Synrutile
Austpac’s synrutile is rich in titanium dioxide (over 97% TiO2). TiO2 pigment is used in the manufacture of paints, plastics, paper, ink, rubber, textiles, cosmetics, leather and ceramics. It is also used in photovoltaic panels to increase solar cell efficiency, for the removal of airborne pollutants and in ‘self-cleaning’ paints. About 95% of world TiO2 feedstock production is used to produce titanium dioxide pigment.
The ultra-high TiO2 content of Austpac’s synrutile also makes it suitable for the production of titanium metal. Titanium metal’s light weight, combined with great strength, corrosion resistance and high melting point make it ideal for use in aircraft engines, cars, sports equipment (golf clubs, tennis racquets and bicycle frames), and general industrial equipment. Only about 5% of the world’s titanium is used as metal.
Uses of Austpac Direct Reduced Iron|
Austpac’s EARS acid regeneration process was developed to recycle iron chloride solutions and produce strong hydrochloric acid and iron oxide, which is then reduced to iron (metal pellets), termed Austpac Iron. Austpac has the only process that is capable of producing strong acid and iron metal directly from chloride solutions, and the only synrutile process that produces a valuable co-product.
The EARS/Metallisation process can be used to recycle spent liquor from steel pickling operations, and at same time as recovering iron from waste iron oxide solids produced by the steel-making process.
Austpac Iron may be used in foundries for specialist castings, in electric arc furnaces to make steel, in basic oxygen furnaces to adjust the composition of the steel melt, and for cementation.
Uses of Hydrochloric Acid (HCl)
Austpac’s patented EARS system regenerates strong hydrochloric acid from iron chloride solutions (both from its own process and liquid steel mill wastes). HCl is used to leach iron from ilmenite, for steel pickling and for swimming pool acidification.
