Alteration of chrome-to-iron ratio in chromite ore by

Although South Africa holds three quarters of the world's chromite ore reserves, the chrome-to-iron (Cr-to-Fe) ratio of the local chromite ores is relatively low (1.47 to 1.55), compared to other deposits in the world (2.6 to 3.5). Additionally, iron is more readily reduced than chromium.

Effect of Chrome Ore Quality on Ferrochrome Production

3. METALLURGICAL BEHAVIOR OF CHROME ORE 3.1 Reducibility Reducibility of ore, as has been indicated before [1, 2], is determined by its mineralogy (MgO/Al2O3 ratio), the MgO structural form in the chrome ore, chromite grain size, the extent of grains distribution in ore and the ore melting temperature.

Much 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 chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used.

Ferrochrome Wikipedia

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 chromite.Most of the global output is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.. Increasing amounts are coming from Russia and
