Aluminum (or aluminium) is a chemical element—a metal—with the symbol AL and atomic number 13. It is the third most abundant element and the most abundant metal in the Earth’s crust. Of the Earth’s solid surface, 8% by weight is aluminum but its chemical reactivity tends to combine it with over 270 different minerals.
The smelting of the ore, bauxite is one of the most common methods of producing ‘primary’ aluminum. Canada is the third largest aluminum producer in the world after Russia and China—second and first—by a wide margin—respectively.
