The majority of world crude steel is made from the BFBOF route. Ores carrying very high quantities of hematite (greater than ∼60% iron) are known as "natural ore" or DSO, meaning they can be fed directly into the BFBOF route. However, lowgrade ores need to be beneficiated before they can be used to make steel.
