Comminution and classification technologies of iron ore
The majority of world crude steel is made from the BF-BOF 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 BF-BOF route. However, low-grade ores need to be beneficiated before they can be used to make steel.
