The pretreatment process includes grinding iron ores to have a very fine texture, normally to enrich the quality of the ore, remove gangues containing impurities (sulfur and phosphorus), and for controlling the size of the grains.

The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5)(OH) 4) and gibbsite (Al(OH) 3). Some progress has been made in using flotation to separate kaolinite from hematite. High levels of phosphorus in iron ore attract a penalty because this makes steel brittle.

Regardless of how phosphate ore is extracted, it contains impurities that must be removed before it can be used for the manufaൣture of fertilizer. Among the common impurities are clay minerals, sand ⠀ , carbonates, iron oxides, and others.

Grinding and separation are performed alternately, which ensures that impurities are separated from the slurry and that the iron content is raised, to around 68 per cent. Flotation Through a chemical treatment known as flotation, the ore is further purified, for example of the phosphorus mineral apatite.
