To find the cost to produce the aluminum in one standard can from bauxite ore, calculate the cost to produce 1 kg of aluminum from bauxite by multiplying the electricity required (30 kWh) by the cost of electricity per kWh ($0.08), and then determine the cost per can by scaling this cost down to the weight of one can (13 grams).

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.
Bauxite, the principal ore used for aluminum smelting, is named after Les Baux, Provence, the village where the first deposits were discovered. Bauxite contains hydrated alumina equivalent to as much as 40–60% Al 2 O 3, and is free of the other siliceous materials leached out over time. However it still contains 10–30% iron oxide, and some ...
Bauxite Ore Processing. Aluminum is found in varying amounts in nature as aluminosilicates (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 3.xH 2 O, known as bauxite. The bauxite is purified by the Bayer Process. First ...
