The commonest of these ores is chromite, a natural oxide of iron and chromium, which in some cases contains oxides of magnesium, aluminum and silicon. Chromium is generally extracted from its ores by oxidation in the form of chromate, in which state its valence is six. The product of this reaction is then treated to extract the chromate.
· The effective extracting Cr (VI) from chromite ore processing residue (COPR) is the key to achieve COPR detoxification and recovery. We developed an effective method to extract Cr (VI) from COPR via controlling the phase transformation of Cr (VI)containing minerals.
