The alumina powder is shipped to aluminum smelters worldwide where it is smelted and cast into aluminum billets, blocks, and ingots before being cut to manageable sizes using large circular
the process needs a large amount of thermal energy. The end product of the alumina plant is a dry white powder that is the feedstock for aluminum smelting. 2.2 Primary Aluminum Production Throughout the world, primary aluminum is still produced by the electrolysis of alu-mina in molten fluoride salt.
In smelting, a key chemical change occurs to the materials being processed; in this case, aluminium separates from the raw ore. It is a process used for extraction to remove useful metals from ore, rather than to process metals already in pure or alloy form, as is the case with melting. Once smelting is complete and metal is purified, melting

Aug 16, 2012· Bauxite is then converted into aluminum oxide, or alumina, using natural gas at plants located in the southern United States. After alumina is extracted from bauxite ore, further processing called 'smelting' is necessary to convert it into aluminum. In this process, alumina is dissolved in a solution and a strong electric current is applied.
May 08, 2014· Industrial production of primary aluminum is carried out by the Hall–Héroult process, named after its inventors, who independently of each other, in 1886, developed and patented an electrolytic process in which aluminum oxide (or alumina, Al 2 O 3) is dissolved in an electrolyte consisting mainly of molten cryolite (Na 3 AlF 6) and aluminum fluoride (AlF 3).
