In Situ Bioremediation of Chromium (VI) In a Simulated Ferrochrome Slag
Stability of chromium in the tailing dumps and stockpiles of chromium concentrate at chrome mining fields is affected by pH, redox potential, and the presence of other metallic species in the waste rocks. It is desirable to keep chromium in the dump site

Combined Treatment of Cr(VI)-Contaminated Soils by Reduction, Adsorption, and Solidification
Remediation of Cr(VI)-contaminated soil usually includes reducing Cr(VI) to Cr(III) with sub-sequent solidification. In this paper, a treatment technique that combines reduction, adsorption, and solidification was proposed.
