ferrochromium is to create a region in the furnace that is oxidizing to the chromium carbide with the use of a high density-high smelting ore. The high density (approx. 4 g/cm') will allow it to pass through the low density slag (-3 gl cm') and form a chromic oxide rich layer above the molten ferrochromium 191Disposal of ferrochromium slag, a major industrial solid waste generated during production of ferrochromium alloy has been a serious problem owing to the presence of 7.8–12.0% residual chromium in it.

Ferrochrome (FeCr) is the main source of virgin chromium (Cr) units used in modern-day chromium (Cr) containing alloys. The vast majority of produced Cr is used during the production of stainless steel, which owes its corrosion resistance mainly to the presence of Cr.
