Chromite - Wikipedia
Chromite is a mineral that is an iron chromium oxide. It has a chemical formula of FeCr2O4. Other minerals with a lower resistance are seen to alter in this series to minerals such as serpentine, biotite and garnet. Cr-VI is produced from Cr-III by means of dry milling or grinding of the ore. This mostly has to do with the
