Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. Alumina refineries tend to be located close to bauxite mines and/or ports for efficient transport of raw materials and of the final product.
By X-ray powder diffraction, diaspore, kaolinite, illite, anatase, hematite, and quartz were determined as the main minerals in bauxite tailings. The bauxite tailings were milled for 5 h using a planet-ball mill to reduce particle size. The particle size of the milled bauxite tailings ranged from 0.02 to 50 μm.
