    Smelting Extracting and Refining AluminumBillet DevelopmentExtrusion ProcessAlumina is dissolved in reduction pots; these are deep rectangular steel shells lined with carbon or graphite. The steel shells are filled with a molten electrolyte consisting mostly of a compound of sodium, aluminum, and fluorine, called cryolite. Carbon anodes are immersed into the electrolyte carrying electrical current which then flows into the molten cryolite containing dissolved alumina. The chemical bond between aluminum and oxygen in the alumina is broken, the aluminum is deposited in the bottom
