The moisture content of pre-grinding of fine iron ores, near 3–5%, could very well be handled and obviously would reflect the ore moisture as supplied to a plant. A higher moisture content could well be accepted in the first stages, although it would pose a limit to the dry screening in the intermediate stage.

It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.
