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.
