Aluminum is the most abundant metal element in the Earth's crust. Bauxite ore is the main source of aluminum and contains the aluminum minerals gibbsite, boehmite, and diaspore. Aluminum is used in the United States in packaging, transportation, and building. Because it contains several minerals, bauxite itself is a rock, not a mineral.
Over its lifetime, every kilogram of aluminium that replaces heavier materials in a car or light truck can save a net 20 kilograms of carbon dioxide emissions. Aluminium is made from bauxite, or aluminium ore. Bauxite is the basic raw material that is refined into alumina, which in turn is sent to smelters for processing into aluminium.

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, Australia and the Caribbean. Step 2: Refining ...
New Scrap is surplus material that arises during the manufacture and fabrication of aluminium products, up to the point where they are sold to the final consumer. For example, off cuts of aluminium sheet or extrusions are considered new scrap. Sometimes, this new scrap can be safely recycled by aluminium smelters as its composition is …
