Aluminum is the second most abundant metallic element in the Earth's crust after silicon, yet it is a comparatively new industrial metal that has been produced in commercial quantities for just over 100 years. It weighs about one-third as much as steel or copper; is malleable, ductile, and easily machined and cast; and has excellent corrosion ...
During the smelting operation, some of the carbon is consumed as it combines with oxygen to form carbon dioxide. In fact, about half a pound (0.2 kg) of carbon is used for every pound (2.2 kg) of aluminum produced. Some of the carbon …
Alumina is used for the production of aluminium metal, through the Hall–Héroult electrochemical smelting process. It is also used in applications such as industrial and medical ceramics, sandpapers, pigments, cosmetics and pharmaceuticals. The Bayer Process is the most economic means of obtaining alumina from bauxite.

After bauxite mining, the bauxite rock ores are crushed using grinding mills. Then ore conveyors are used to transporting the prepared aluminum oxide. Bauxite is processed to make aluminum oxide before it is processed further to make aluminum, which requires electrolysis (Haraldsson and Johansson, 2018; Murray, 1999).
A substantial amount of aluminum is also recycled at such smelters. Concerns related to aluminum mining include the release of aluminum into the air, which settles into water systems making it toxic to water-dwelling organisms. Aluminum may also disrupt plant growth in acidic soils. The aluminum smelting process releases harmful greenhouse gases.
