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 0.15 mm to 10 mm. Pellet feeds have the size of less than around 0.15 mm. Concentrate is the ore which has been enriched by the beneficiation process.

In medium and small iron ore concentrators, two-stage crushing processes are generally used. This process can be used when the size of the raw ore is small or the required crushing is small. If the granularity of the crushed product is not strict, the open circuit process can be used. Otherwise, a closed-circuit process should be used.
