Characterisation and liberation of chromium from fine ferrochrome waste materials

Van Staden, Y.; Beukes, J.P.; Van Zyl, P.G.; Dawson, N.F.; Du Toit, J.S. (Elsevier, 2014)

Three types of generic chromium (Cr)-containing wastes are generated during ferrochrome (FeCr) production, i.e. slag, bag filter dust (BFD) and venturi sludge. Slag is by volume the largest waste; however, fine FeCr waste ...
Liberation of chromium from ferrochrome waste materials utilising aqueous ozonation and the advanced oxidation process

Van Staden, Yolindi (North-West University, 2014)

During ferrochrome (FeCr) production, three types of generic chromium (Cr) containing wastes are generated, i.e. slag, bag filter dust (BFD) and venturi sludge. The loss of these Cr units contributes significantly to the ...
