Energy consumption

Energy needed to produce aluminum Today in Energy

2012-8-16  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. This process has generally remained unchanged since its invention in 1886.

Aluminum facts NRCan

2021-8-18  Aluminum does not exist in a pure state in nature. The production of primary aluminum metal begins with bauxite ore, which is composed of hydrated aluminum oxide (40% to 60%) mixed with silica and iron oxide. It takes approximately 4 to 5 tonnes of bauxite ore to produce 2 tonnes of alumina.

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.
