Process for extracting chromium from chromium ores ...

Chromium occurs with a valence of three in its naturally occurring 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.
