Primary Production - The Aluminium Story

  • Refining Process

    The Bayer Process, a thermo-chemical digestion method invented in 1887 by Austrian scientist Karl Josef Bayer, is the most economic means of obtaining alumina from bauxite. | Learn more

  • Smelting Process

    The Hall-Héroult process, the industrial method for the smelting of primary aluminium, involves passing a large electric current through a molten mixture of cryolite, alumina and aluminium fluoride to obtain liquid aluminium metal. | Learn more

  • Aluminium Semi-Fabrication

    The benefits of aluminium – its low density, strength, ductility and corrosion resistance – are realised through a number of processing methods, to produce semi-finished products, that will become window frames, electric cables, car parts, cans and foils. | Learn more

Demand for aluminium products has doubled since 2000

Aluminium is a silvery-white metal, the 13 element in the periodic table. One surprising fact about aluminium is that it's the most widespread metal on Earth, making up more than 8% of the Earth's core mass. It's also the third most common chemical element on our planet after oxygen and silicon

Light, durable, malleable and corrosion-resistant: these are the qualities that make aluminium one of the key engineering materials of our time. We can find aluminium in the homes we live in, in the automobiles we drive, in the trains and aeroplanes that take us across long distances, in themobile phones and computers we use on a daily basis, in the shelves inside our fridges and in modern interior designs.
