| Abstract: | By using a two-stage carbon reduction process, Cr~(6+) may be effectively reduced to Cr~(3+) or even metallic Cr. At Shaoguan Iron and Steel Group Company (SISG), the chromium constituent in the chromium-bearing slag was recovered by making an effective use of the sintering and iron-making processes; and the slag was detoxified, thus becoming harmless and recyclable, through a high temperature reduction of the carbon monoxide by the carbon generated in the sintering and iron-making processes. |
