use of water in bauxite process

Bauxite: The principal ore of aluminum.

The most important barrier to remediation, use and long term sustainability of bauxite residue management is its high alkalinity. Bauxite residues and the runoff from storage areas can be treated to reduce their pH, further reducing the risk of environmental impacts and facilitating rehabilitation of the disposal area after closure.
