What Is Aluminum Smelting? (with picture)

Secondary aluminum smelting is a bit different because it involves extracting the metal from scrap materials or byproducts known as dross, which are created during primary aluminum smelting.When recovery is simply from scrap, the material is usually melted in a gas reverberatory, an oil reverberatory, or a hearth furnace.

Cryolite Bath Chemistry

The bath composition in an aluminum reduction cell is very important. Some components like aluminum fluoride or alumina are deliberately added while other come as impurities from the alumina. The cryolite in the molten state is decomposed into different ionic species. At the anode and cathode occurs different reactions, driven by the electrical current, which overall produce the aluminum.
