Two different chromite ores from local sources, sandy chromite ore from Opol, Misamis Oriental (SCO) and lumpy chromite ore from Manticao, Misamis Oriental (LCM) were used in the study. Isothermal and non-isothermal experiments were conducted in a fixed bed reactor heated in a vertical tube furnace in the temperature range 800 to 1000°C.
Chromite, an oxide of iron, magnesium, aluminum, and chromium, is the only ore mineral of chromium. In nature, chromite deposits are generally of two major types: stratiform (layered) and podiform (pod shaped). Both types are associated with ultramafic igneous rocks. The world's largest stratiform chromite deposits are found in South
ore production in various forms of imported materials, such as chromite ore, chromium chemicals, chromium ferroalloys, chromium metal, and stainless steel. One U.S. company mined chromite ore in Oregon. Imported chromite was consumed by one chemical firm to produce chromium chemicals. One company produced chromium metal.
PRODUCTION OF CHROMIUM IRON ALLOYS . DIRECTLY FROM CHROMITE ORE .

Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron.

Chromite was first discovered on Scottie Creek, which lies 4 km morth of the Ferg Claim, in 1901. Approximately 454 tonnes of chromite ore was mined in 1918. Consolidated Mining and Smelting Company of Canada drove test adits on the Scottie and Ferguson Creeks showing between 1927 and 1931. Eight claims were Crown granted on Scottie Creek.
3. Commercial chromite ore beneficiation processes. Pure chromium is difficult to produce since it is readily contaminated by many other elements. Huge quantity of raw chromite ore is being mined and beneficiated in various chrome ore beneficiation plants throughout the world to cater the customized needs of various ferro alloy plants.

The chromite ore in the Chickay Mine is in the form of a vein of complicated shape. Due to depletion of high grade chromite ore, and the presence of a large amount of low-grade ore in the area, it was necessary to come up with a suitable mineral processing technique to upgrade these low-grade ores together with the leftover fines
