Why is Chromite Important for Renewable Energy Use? Chromite is the only ore of chromium, making it especially important for mining and obtaining chromium. Geoscientists claim there are nearly “11 billion tons” of chromite in the world, making it plentiful and abundant. With this amount of chromite available, renewable energy sources can be sustained for years.

1015· Chromium ore processing residue (COPR) is a hazardous waste generated during the production of chromate. Currently, approximately 10% of Cr2 O 3 cannot be extracted after chromite sodium roasting and remains in COPR, wasting valuable Cr resources. In this study, Mg was selectively removed by using (NH4) 2 SO 4 roasting in combination with H 2 …

To extract chromium from chromite ore, start by roasting chromite with sodium hydroxide (NaOH) or potassium hydroxide (KOH) in the presence of oxygen at high temperatures. During roasting of chromite ore with NaOH/KOH in the presence of oxygen, chromium is oxidised from Cr3 + to Cr6 + and reacts with alkali to form chromate compounds.

How chromite is extracted from its ore? Extraction. Chromite (FeCr2O4) is the most commercially useful ore, and is extensively used for extraction of chromium. This is obtained by aerial oxidation of chromite in molten alkali to give sodium chromate, Na2CrO4, which is leached out with water, precipitated and then reduced to the Cr (III) oxide by carbon.
