    Chromite ore processing residue (COPR) poses a great environmental and health risk with persistent Cr (VI) leaching. To reduce Cr (VI) and subsequently immobilize in the solid matrix, COPR was incubated with nanoscale zero-valent iron (nZVI) and the Cr (VI) speciation and leachability were studied. Multiple complementary analysis methods including leaching tests, X-ray powder diffraction, X-ray absorption near
