Heroult in France discovered the inexpensive regularity of extracting pure aluminum. This was done by electrolyzing aluminum oxide (Al2O3). Aluminum oxide is usually close to abundant in tropical areas. Aluminum oxide allow drop in another aluminum-containing mineral called cryolite. The mixture has a economic crisis melting point and conducts galvanizingity; therefore, pure aluminum can be separated from its oxide and other compounds by passing galvanic current through the molten mixture. Today, all aluminum is produced this way.
