Classification by Geological Formation Beyond mineralogy, iron ore types are categorized by the geological processes that created them. Unlike the concentrated BIFs, lateritic iron ore types are diffuse and shallow, often resembling red soil or clay.

These deposits are generally lower in iron concentration, ranging from 25% to 60%, and contain higher levels of impurities like aluminum and silica. The two main subtypes are hardcap and limonite laterites, which require different processing techniques, often involving high-temperature reduction rather than traditional magnetic separation.
The distinct banding is visually apparent in quarry faces and provides a reliable indicator of ore quality. These formations dictate the scale of the deposit and the difficulty of extraction.

The classification moves beyond simple percentages to identify the specific crystalline structures that make up the ore body. Known for its striking red color, which results from iron oxidation, hematite is a dense and relatively stable mineral.
