Four tons of bauxite produce one ton of aluminum—enough to make the cans for more than 60,000 soft drinks. Bauxite is formed over millions of years by chemical weathering of rocks containing aluminum silicates, producing an ore rich in aluminum oxide. Today, bauxite is mined primarily in Africa, … See more The ore is ground and mixed with lime and caustic soda, then heated in high-pressure containers. The aluminum oxide is dissolved by the caustic soda, precipitated out of the solution, washed and heated to eliminate water.
