Simultaneous oxidation of Cr(III) and extraction of Cr(VI)
2019-9-1 When the concentration of Na 2 SiO 3 increased to 25 mM, corresponding to 1.25 mol per kg COPR, Cr (VI) extracted from COPR reached the maximum of 116.0 mg L -1. However, upon a higher Na 2 SiO 3 dosage of 150 mM, the Cr (VI) extraction didn’t further increase, meaning that the extraction of Cr (VI) from COPR is saturated with 25 mM Na 2 SiO 3.

Process for extracting chromium from chromium ores
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.
