Most commercially produced aluminium is extracted by the Hall–Héroult process. In this process aluminium oxide is dissolved in molten cryolite and then electrolytically reduced to pure aluminium. Making aluminium is very energy intensive. 5% of the electricity generated in the USA is used in aluminium production.

With the two processes combined, bauxite ore can be processed into alumina, which is then converted into aluminum. Today, the Bayer process is virtually unchanged and is used to produce nearly all of the world's alumina supply, as an intermediate step in aluminum production. Industrial uses of alumina. In addition to its use in the production of primary aluminum, aluminum oxide has other key industrial .

4. Shredding. After the crushing and breaking of the metal, the shredding process starts. The metals are broken down into tiny pieces or sheets to allow further processing. The small pieces have large surface to volume ratio that can be melted using less energy as compared to when they are in large pieces of metal.
However, today there is a good thrust to foundry technology and the trend of induction furnace application is just in its prime age. Its application is mostly in smaller foundries for iron melting. The induction furnace consists basically of a crucible, inductor coil, and shell, cooling system and tilting mechanism.
