Recovery of chromium from ferrochrome slag

Abstract

Ferro chrome slag may contain chromium in +3 and +6 oxidation states. Separation and determination of chromium content of the slag samples collected from Jindal Ferro Alloys Corporation, (Kottha valasa, Visakhapatnam Dt.) has been carried out following extraction with benzene solutions of TOAO(0.01M). Maximum extraction efficiency was achieved at pH 2.5M in presence and absence of impurities associated with ferrochrome slag. The results obtained in the present study are compared with synthetic as well as slag samples (as per the specifications of manufacturers).
