Aluminum Production - an overview ScienceDirect Topics

Feb 05, 2011  In this process, the aluminium is connected to a circuit, as shown in Fig. 31.4, where it forms the anode. The solution is prepared so that, rather than removing metal from the anode, the process significantly increases the thickness of the oxide layer, and enhances corrosion resistance. It may also be used to make an attractively coloured ...

Hall–Héroult process - Wikipedia

The Hall–Héroult process is the major industrial process for smelting aluminium.It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium's chief ore, through the Bayer process) in molten cryolite, and electrolysing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process applied at industrial scale happens at 940–980 °C and ...
