  • Aluminum, the Miracle Metal | The Aluminum Association

    The Bayer process, discovered in 1887, is the primary process by which alumina is extracted from bauxite. When refined from bauxite, alumina generally looks like a white powder similar to table salt or granular sugar. To produce pure aluminum, alumina is smelted using the Hall–Héroult electrolytic process to make primary aluminum.
