APPLICATIONS"Bauxite, an aluminium ore, is the world's main source of aluminium. It consists mostly of the minerals gibbsite Al(OH)3, boehmite γ-AlO(OH) and diaspore α-AlO(OH), mixed with the two iron oxides goethite and haematite, the clay mineral kaolinite and small amounts of anatase TiO2. Calcined Bauxite is used as raw material for manufacturing fused alumina and high alumina refractories. On an average 4-5 tonnes of bauxite are needed to produce two tonnes of alumina from which only one tonne of aluminium can be produced. Aluminium is possibly the most versatile product with applications in almost every industry and since bauxite is the primary source for aluminium it will always be in great demand. 15% of bauxite goes into refractory, chemical , cement ,abrasives and other applications.
Application:
- In construction concretes, rapid strength development is achieved, even at low temperatures.
- In construction concretes, high chemical resistance is possible.
- In refractory concretes, strength is maintained at high temperatures.
- As a component in blended cement formulations, various properties such as ultra-rapid strength development and controlled expansion can be obtained.
