Aqueous solubility speciation of Cr(VI) in ferrochrome bag filter dust
(North-West University, 2015)
The production of ferrochrome (FeCr) from chromite ore is a reducing process, whereby the Cr(III) and Fe(II) in the ore are reduced to metallic chromium (Cr) and iron (Fe) in the final product. FeCr is mostly used for the ...
