| Abstract Scope |
The growing stockpiles of bauxite residue and associated environmental hazards require a sophisticated process flowsheet for sustainable residue management and value recovery. Considering the association of multiple elements (Fe, Al, Si, Ca, Ti, V, Sc) within bauxite residue, metal extraction is of prime interest. The complex association of different elements and physical and chemical characteristics makes the extraction and purification process expensive and challenging. The present study focuses on developing a novel hydrometallurgical flowsheet for subsequent recovery of base metals and critical elements from bauxite residue. The major elements present in bauxite residue are recovered as high purity magnetite, alumina, titania, silica and calcium carbonate. Whereas critical elements (such as V and Sc) are recovered in the liquid stream generated after the recovery of base metals |
