Aluminium life cycle - Norsk Hydro
Aluminium production starts with the raw material bauxite, which contains 15-25 percent aluminium and is mostly found in a belt around the equator. There are around 29 billion tonnes of known reserves of bauxite and at the current rate of extraction, these reserves will last us more than 100 years. There are, however, vast undiscovered resources that may extend the time perspective to 250-340 ...
