Alumina: Filtration in the alumina production process - .

The production of alumina from bauxite is a hugely significant industry in its own right but it is also one of the most significant global users of filtration and separation technology. A typical alumina plant may use approximately 500–1000m2 of filtration area per million tonnes of production (as well as many hundreds of square metres of gravity thickener/clarifier area).
