• 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).

  • How Aluminum is Produced

    The smelting process required to produce aluminum from the alumina is continuous the potline is usually kept in production 24 hours a day yearround. A smelter cannot easily be stopped and restarted. If production is interrupted by a power supply failure of more than four hours, the metal in the pots will solidify, often requiring an expensive rebuilding process.
