Bauxite Mining and Alumina Refining: Process Description and LWW
The bauxite ore contains aluminum trihydrate (Al(OH) 3). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3: The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite. Bauxite residues are then

The Environmental Impact of Aluminum (And Why it’s Still
2017年9月21日Bauxite is collected from the ground in an open-pit mining operation. It doesn’t sit very deeply in the earth’s crust, so some energy can be saved on drilling. However, to recover all the aluminum in an area, swaths of land must be bull-dozed to reveal the dirt and ore underneath. Once collected, the bauxite ore has to be refined.
