12.1 Primary Aluminum Production

12.1 Primary Aluminum Production

12.1.2 Process Description 2-3 Primary aluminum production begins with the mining of bauxite ore, a hydrated oxide of aluminum consisting of 30 to 56 percent alumina (A l2O3) and lesser amounts of iron, silicon, and titanium. The ore is refined into alumina by the Bayer process. The alumina is then shipped to a primary aluminum plant for ...

How Aluminum Is Produced

How Aluminum Is Produced

The smelting process required to produce aluminum from the alumina is continuous the potline is usually kept in production 24 hours a day year-round. A smelter cannot easily be stopped and restarted. If production is interrupted by a power supply failure of more than four hours, the metal in the pots will solidify, often requiring an expensive ...

Environmental Guidelines For Aluminum Manufacturing

Environmental Guidelines For Aluminum Manufacturing

both aluminum quality and air emissions. The prevailing process for secondary aluminum production is smelting in rotary kilns under a salt cover. Salt slag processing and re-utilization is possible. Other processes, smelting in induction furnaces and hearth furnaces, need no or substantially less salt and are associated with lower energy demand.
