  • Aluminium mineral extraction– open pit surface mining
    Aluminium mineral extraction– open pit surface mining

    Since bauxite is an aluminium ore aluminum is thus produced by separating aluminium oxide from iron oxide present in bauxite This process allows bauxite to be mixed with caustic soda or sodium hydroxide and then heated under pressure after which the sodium hydroxide dissolves into aluminium oxide forming sodium aluminate whereas the iron oxide remains solid and is separated by filtration
