Energy needed to produce aluminum
Primary production starts with bauxite ore, which, in the United States, is usually imported from Jamaica and South America. 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' …
