  • The Process of Mining Bauxite

    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

  • Bauxite mining in the United States Wikipedia

    Bauxite forms by the weathering of aluminum-rich and silica-poor rocks in hot, humid, climates, at places with good drainage. Under the proper conditions, weathering disintegrates the aluminium silicate minerals, and dissolves and removes the silica, creating bauxite. The mined US bauxite deposits have all been in the southeastern United States.
