Aluminium production process

The ore is loaded into autoclaves and treated with lime–caustic soda. Aluminium oxide appears in the resulting slurry while all the admixtures settle to the bottom as red mud. The sodium aluminate solution is stirred in precipitators for several days, eventually pure alumina or Al 2 O 3 settles at the

The history of aluminium industry

Humankind came across aluminium long before the metal we know today was produced. The Natural History by Pliny the Elder, a Roman scientist, told the story of a first century craftsman presenting a cup made of an unknown metal looking like silver, but too light to be sliver, to Tiberius, the Roman Emperor. Alum, an aluminium-based salt, was used extensively in ancient times.
