In case of dry grinding, the iron ore fines are dried in a separate dryer to reduce moisture content to less than 1%. The dried fines are fed to grinding mill. It is desirable to add flux materials and/or bentonite with the iron ore fines in case of dry grinding, which has an additional advantage of elimination of mixing stage.

Iron ore is also classified as per its size and the processing method. Lump ore has the size of around 10 millimetres (mm) to 40 mm. Ore fines have the size of around mm to 10 mm. Pellet feeds have the size of less than around mm. Concentrate is the ore which has been enriched by the beneficiation process.
