Abstract
The present invention relates to method and a system of reducing chromium (VI) from a chromium bearing solution. The reduction of the chromium (VI) is achieved by contacting the chromium bearing solution which comprises chromium (VI) ions in an aqueous solution with iron fibers in an exchange mass under oxidation-reduction potential conditions at a pH of at least 2.5, with entry of iron ions into solution in the aqueous solution and reduction of the chromium (VI) ions to chromium (III) recovered in the exchange mass. A solution substantially free of chromium (VI) ions and total chromium is produced and discharged from the exchange mass.
