Aluminium
Pure aluminum is made from bauxite, a kind of rock that has aluminum oxide and many impurities. The bauxite is crushed and reacted with sodium hydroxide. The aluminum oxide dissolves. Then the aluminum oxide is dissolved in liquid cryolite, a rare mineral. Cryolite is normally produced artificially though. The aluminum oxide is electrolyzed to make aluminum and oxygen. The largest producer of aluminum is China. China produces about 31,873 thousand tonnes of aluminum.
