| 18992990 | Moon DH, Wazne M, Koutsospyros A, Christodoulatos C, Gevgilili H, Malik M, Kalyon DM: Evaluation of the treatment of chromite ore processing residue by ferrous sulfate and asphalt. J Hazard Mater. 2009 Jul 15;166(1):27-32. Epub 2008 Sep 27. The combination treatment of ferrous sulfate and the encapsulation of the treated COPR into asphalt reduced the TCLP total Cr concentration to lower than the regulatory limit of 5mg/L for Cr contaminated soils, after 16 months. |

Effect of iron (II) addition on (VI) leaching from columns of chromite ore processing residue. Environ Sci Technol. 2003 Jul 15;37(14):3206-13. Ferrous sulfate, which is used for remediation of Cr (VI) contamination in wastewater and soils via reduction to Cr (III) and subsequent precipitation of iron (III)/ (III) has also been proposed for remediation of Cr (VI) in COPR. |

Sci Total Environ. 2006 Jul 1;364(1-3):32-44. Epub 2006 Jan 26. Past disposal of high-lime chromite ore processing residue (COPR) from a chemical works in S.E. Traditional methods of remediating Cr (VI)-contaminated land, e.g. using ferrous sulfate and organic matter, have had limited success in converting Cr (VI) to less harmful and insoluble Cr (III). |
