  • The smelting process Boyne Smelters

    To make aluminium, large blocks of carbon called anodes are placed into a special bath material containing alumina. An electrical current is passed through, leaving behind molten aluminium. This is then cast into different shapes, ready to be sold on to customers. ...

  • Aluminium smelting - Wikipedia

    Aluminium smelting is the process of extracting aluminium from its oxide, alumina, generally by the Hall-Héroult process. Alumina is extracted from the ore bauxite by means of the Bayer process at an alumina refinery. This is an electrolytic process, so an aluminium smelter uses huge amounts of electricity; smelters tend to be located close ...

  • European Aluminium - 89436FB4-F448-451F-94E8

    Aluminium production begins with bauxite, the aluminium ore. Most bauxite is mined in tropical areas, with around 50km 2 of new land mined each year. At the same time, a matching area of land is restored to nature. Pure aluminium oxide, called alumina, is ...

  • The Aluminum Smelting Process and Innovative

    8/5/2014· In addition to being the raw material for production of aluminum, alumina also acts as a thermal insulator when it is placed on top of the self-formed solid crust above the electrolyte, thereby reducing heat losses. Alumina is also used for covering the top of the

  • Aluminium production process

    At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950 . Electric currents are then induced in the mixture at 400 kA or above; this current breaks the bond between the aluminium and oxygen atoms resulting in liquid

  • How to Build an Aluminum Smelter Sciencing
