why is bauxite important - Lisbdnet
Why Is Bauxite Important? Bauxites are industrially important for both Al metal supply and non-metallurgical use and they represent the only raw material used in the production of alumina on a commercial scale. Gallium is a common by-product of Al extraction from bauxites, and they may also be considered as a possible future resource for REE.
