· Aluminum is the most abundant metal element in the earth''s crust, but it is always found in a compound rather than an easily-refined ore. Alum is one such compound. Scientists tried to tease the metal out of alum, but the process was costly until Charles Martin Hall patented an inexpensive method to produce aluminum in 1889.
More DetailsALUMINA PRODUCTION. Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste that is collected in special containers and heated with steam to remove most of the silicon present in bauxites. The ore is loaded into autoclaves and treated with lime–caustic soda.
