How aluminum is made – Primary Production Process

To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process. This process is referred to as primary production.

Primary production is the process through which new aluminum is made. Primary production is the process by which alumina is smelted to pure aluminum metal, the main industrial aluminum smelting process by which primary aluminum is made is Hall–Héroult electrolytic process. Aluminum originates from bauxite, aluminum within the bauxite ore is chemically extracted into alumina, alumina is smelted into pure aluminum metal through the Hall–Héroult aluminum smelting process.

In the Hall–Héroult aluminum smelting process, alumina is dissolved in a molten cryolite bath within a carbon-lined steel pot. Carbon anodes (pre-baked anode carbon blocks) are inserted in the top of the bath and an electric current passes through the anodes and the bath. Oxygen atoms separate from the alumina and combine with the carbon anode, leaving the remaining molten aluminum at the bottom of the pot. The molten aluminum is periodically siphoned out and placed in a holding furnace. From the holding furnace, the molten aluminum is cast into an aluminum ingot.
