Abstract

Vanadate sludge obtained as a by-product during Bayer's process contains fairly higher quantity of precious metal vanadium as vanadium oxide ( 5- 20% ) along with other impurities like sodium, aluminium and phosphorus salt. The present invention relates to a process for recovering vanadium oxide from vanadate sludge obtained from Bayer's process. The effluent generated during the process is recycled and the impurities such as sodium, aluminium and calcium are recovered as valuable by-product.
