Chromium: Ferrochrome prices continue to diverge from chromite
· The chromite ore industry, however, has not seen the same gains as many producers operate at a loss given the higher costs to bring material to market ( to China). EndJuly chromite prices for primary chromium ores in South Africa are up only 20% compared to endNovember 2020, versus the 70% gain for ferrochrome.

Technology Innovations in the Smelting of Chromite Ore
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). With this problem, it means that fine chromite ores are not of economic value. However, with the development of the Premus technology,

Chromite Processing Ferrochromium
Chromium processing deposits are mined by both underground and surface of the ore is rich enough to be used directly for production of ferrochromium, a rich, lumpy ore containing more than 46 percent cr 2 o 3 and having a chromiumiron ratio greater than 21 is preferred, but ores with a lower ratio and as little as 40 percent cr 2 o 3.
Ferrochromium Alloys Manufacturing
· Domestic chromite resources are small in size, low in grade, and high in iron. Consequently, they are neither competitive with foreign ore nor able to satisfy chromium demand. To help reduce chromite imports, conservation of chromium in metallurgical processing of the chromite ore .
Ferrochrome
Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.

Chromite
Ferrochromium is manufactured by the reduction of the ore. In 2007, the world production of chromite was 20 million tons ( Geological Survey 2008 ). The world resources of chromite are greater than 12 billion tons, and this is, according to the Geological Survey governmental agency, "sufficient to meet conceivable demand for centuries."

The two main products of chromite refining are ferrochromium and metallic chromium; for those products the ore smelter process differs considerably. For the production of ferrochromium the chromite ore (FeCr2O4) is reduced with either aluminium or silicon in an aluminothermic reaction and for the production of pure chromium the iron has to be separated from the chromium in a two step .
