Alumina Refining 101 The Aluminum Association
Alumina is properly called aluminum oxide, which is a chemical compound comprised of aluminum and oxygen molecules (Al 2 O 3 ). When refined from bauxite, alumina generally looks like a white powder similar to table salt or granular sugar. Aluminum oxide is typically referred to as alumina, but may also be called aloxide, aloxite or alundum ...

Case Study: Conversion of Bauxite Ore to Aluminum Metal
Bauxite Ore Processing. Aluminum is found in varying amounts in nature as aluminosilicates (contains aluminum, silicon, and oxygen) in various types of clay. As the minerals are weathered they gradually breakdown into various forms of hydrated aluminum oxide, Al 2 O 3.xH 2 O, known as bauxite.
