Abstract
The present invention concerns a method for the recovery of high purity Cr2O3 from a Na2CrO4 or Na2Cr2O7 solution by producing (NH4)2CrO4 by solvent extraction using an organic solution of a tertiary amine followed by reaction of the organic phase with NH4OH evaporating the aqueous (NH4)2CrO4 and igniting the resulting solids to provide high purity Cr2O3.
