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).
