For these reasons, the rule of thumb is “higher Fe grade, higher price.” Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use in the blast furnace. Lump ore can bypass this process and be charged directly into the furnace, as can pellets, and both command an associated price premium.
