  • Evaluation Of Bridges Constructed In Chromite Ore

    Conversion of Chromium Ore Processing Residue to Chrome Steel Introduction Chromium played an important role in the industrial development of New Jersey from 1905 to 1971. During that period, chromate (Cr6+) was produced from chromite ore at three facilities in Hudson County, NJ.For understanding both the environmental behavior and developing remediation treatments for chromium ore processing residue (COPR) it is important to identify all the potentially soluble sources of Cr(VI). Hydrogarnet has been identified as a major phase in COPR and it has been previously speculated that it has a capacity to host Cr(VI). Here we provide direct evidence of this capacity by.

  • Chromium Ore Processing Residue Maryland

    The geoenvironmental characterization of COPR at two deposition sites (New Jersey and Maryland) included geotechnical, chemical, mineralogical, and leaching analyses of three main chromite ore processing residue (COPR) types [gray black (GB), hard brown (HB), clayey (C)].The efficacious treatment and resource utilization of the chromite ore processing residue (COPR) is important for chromate salt production. In this study, the leaching of valuable elements from the waste COPR was investigated. X ray diffraction (XRD) analysis showed that the COPR mainly contained periclase (MgCr2O4), magnesiochromite ((Fe, Mg) (Cr, Fe)2O4), Fe (Cr, Al)2O4, and MgFeAlO4. The.
