  • 12.4 Ferroalloy Production - US EPA

    Low-carbon (LC) ferrochromium is typically produced by fusing chromium ore and lime in a furnace. A specified amount is then placed in a ladle (ladle No. 1). A known amount of an intermediate grade ferrochromesilicon is then added to the ladle. The reaction is extremely exothermic and liberates chromium from its ore, producing LC ferrochromium ...

    Total world output of ferrochromium in 1992 was 3.579 MMT, of which 619 kMT was produced in Western Europe [Roskill 1993, "Chromium" p. 37]. Assuming ferrochromium accounted for 79% of the chromite ore, with a recovery of 78% [Papp 1994], it would have contained 2.036 MMT Cr in 3.425 MMT ferrochromium.
