Energy Consumption  Process Description  Aluminum is derived from the naturally occurring ore called Bauxite. Bauxite is refined into alumina which is electrochemically reduced into aluminum in reduction cells or pots (Hall-Herault process). The molten aluminum is then either cast into ingots, bars, rolled into sheets, plates or foil, or drawn into rod. These intermediate shapes are then shipped to processing plants which shape the aluminum into consumer products. Click on a process step below for more information.
