- Abstract
The article presents the results of a study which investigated the leaching mechanisms of hexavalent chromium (Cr(VI)) from chromite ore processing residue (COPR) samples obtained from an urban area in Hudson County, New Jersey. In this study batch leaching test, qualitative and quantitative x-ray diffraction (XRPD) analyses and geochemical modeling were used. Experimental and modeling results are explained in terms of potential mineral phases that could be controlling Cr(VI) leaching and the kinetics of dissolution of thermodynamically unstable minerals present on site.
