Description. Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
Chromite. Chromite is the commercial name of iron chromium oxide (FeCr2O4), a mineral comprised of chromium and iron oxide that is naturally found in the earth's mantle. When extracted, it is referred to as chrome ore. Chromite is crucial for the production of ferrochrome, an alloying agent in manufacturing stainless steel.

1. Introduction. Chromite Ore Processing Residue (COPR) is a solid waste generated during the high temperature (∼1200 °C) roasting process that is used to extract chromium from chromite ore (Antony et al., 2006).Lime-based roasting has been the prevalent method to complex other metals in ore (Fe, Mg, Al) and isolate Cr.
Residual unreacted Cr(VI) incorporated in ferrous-sulfate-reduced chromite ore processing residue (rCOPR) can be slowly released during deposition, posing a significant threat to the environment.Recent studies indicate that such Cr(VI) mainly exists within the nano-sized ion channels of ettringite, forming Cr(VI)–ettringite.Therefore, efficient …
