Towards holistic technology solution to chromite ore

Jan 04, 2021 Safe management and disposal of chromite ore processing residue (COPR) is an unsolved global problem. In spite of several global research efforts, the problem of safe management of COPR and redemption of dump sites has remained unsolved. There is a high risk for all living beings in and around the COPR dump sites due to prevailing significant amount of Cr(VI) content in the COPR.

Chromium Remediation or Release? Effect of Iron(II

Chromite ore processing residue (COPR), derived from the so-called high lime processing of chromite ore, contains high levels of Cr(III) and Cr(VI) and has a pH between 11 and 12. 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)/chromium(III) hydroxide, has also been proposed for
