Chromite ore oxidized in air at 900 0C for 2h duration is used as base material for carrying out the reduction studies. During preoxidation of chromite ore, the FeO present in chromite spinel oxidizes to Fe2O3 (sequioxide) in the form of exholved precipitate on the surface of chromite grains and generates cation vacancies.

PRODUCTION, CHARACTERISTICS AND USE OF FERROCHROMIUM

The raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral. Chromite is used as lumpy ores or fine con centrates, which must be generally agglomerated to make them useable charge for the furnace. Fines in the smelting furnace cause unbalanced operation and thus de-crease productivity.

Technology Innovations in the Smelting of Chromite Ore

it is designed for smelting fine chromite ores. The convectional smelting process is designed to handle only lumpy ores which are ideal for ferrochromium production as the fine ores tend to form a sintered layer at the top of the charge, preventing gas escape and thus causing operating difficulties (Buchanan, 2001).

the process of "coarse and fine classification-spiral chute-shaking table-magnetic separation can reduce the cr 2 o 3 grade of laterite nickel ore from 2.24% to 1.27%, and the removal rate of chromite reaches 43.30% calculated by chromium trioxide, which effectively reduces the abrasion of chromite to hydrometallurgical equipment of laterite
