Smelting is a process of applying heat to a metal ore in order to extract the base metal. In the case of aluminium, bauxite is converted into alumina in a facility called refineries and then alumina is transformed into molten aluminium in the smelters. Aluminium production in smelters consists of two process – Primary aluminium production where alumina is smelted to pure aluminium and secondary production is the process of recycling aluminium scrap into aluminium to be used again.
There are three ways to look at aluminium production – country wise production, company wise production and plant wise production.
