An electrical current is run through the mixture, causing the carbon from the carbon anode to attach to the oxygen component in the alumina, yielding aluminum and carbon dioxide: 2 Al2O3 + 3 C > 4 Al + 3 CO2. This process …
The first commercial extraction of alumina (Al 2 O 3) from bauxite has been attributed to Henri Sainte-Claire Deville in about 1854.. Soon after this, in 1888, Karl Joseph Bayer described what is now known as the Bayer Process, which led to a dramatic reduction in the cost of aluminum metal.
