Effect of Chrome Ore Quality on Ferrochrome

Chromium recovery mainly depends on reducibility of the ore. From the input Cr to the furnace, other than recovered Cr to metal, the balance mainly reports to slag and some to furnace dust. With reference to hard and dense ore, the dust portion is low, but depending on ore reducibility and its size, the Cr2O3 content of slag could increase.
