Chromite charge
WebFirst, chromite is one of the more weathering-resistant minerals of peridotite. That causes it to be concentrated in residual soils that form in the weathering zone above chromite-rich rocks. Second, chromite has a … WebThe raw material in the production of ferrochrome is chromite, which is chrome and iron oxides containing mineral. Chromite is used as lumpy ores or fine con centrates, which must be generally agglomerated to make them useable charge for the furnace. Fines in the smelting furnace cause unbalanced operation and thus de-crease productivity.
