Bauxite Mineral Processing Employed
Bauxite residue (BR) is a caustic red-colored by-product of the Bayer process for alumina (Al 2 O 3) extraction from bauxite ore, generated in a proportion ranging from 0.8 to 1.5 (alumina: BR). BR may have distinguished particle's size distribution varying from sand (+100 μm) to fine particles (−150 μm) depending on the bauxite origins.
