Abstract: During the production of alumina from bauxite by the Bayer's process, a sludge containing fairly higher quantity of vanadium is obtained. Various workers have used different methods to recover vanadium from the sludge. Some of these methods either deal with the neutralization of the alkaline sludge followed by the precipitation of vanadates of ammonium or sodium or use lime or other calcium salts to precipitate calcium vanadate. Some techniques involve solvent extraction, and ion-exchange. The paper reviews the work carried out in this direction.
