what 3 ingredients must be added to extract alumina from bauxite

Production of aluminum (emphasis on energy and

For economical extraction, bauxite ores should contain greater than 45% alumina, less than 12% iron oxides and less than 8% of combined silica. The Bayer Process, used to extract the Aluminum from the ore, is so energy-intensive that it takes 95 times more energy to complete this process than to recycle. Get price

High Alumina Cement
