The iron oxide mineral magnetite as Fe 3 O 4 has a mass percent of 72.36% Fe and 27.64% O and typically occurs as a natural ore containing 15–40% Fe. Historically hematite direct shipping ore (DSO) has been the preferred source of iron ore globally, with significant resources located on several continents, including Australia in the Hamersley Range, Western Australia.

The conversion of lepidocrocite (-γFeOOH) to its more stable polymorph, goethite (αFeOOH) was followed by observing changes in crystal morphology, oxalate solubility, surface area and X-ray diffraction. In conjunction, kinetics were measured as functions of surface area, temperature, alkalinity and seeding with goethite crystals.The results suggest that the transformation is not …

Goethite occurs with colloform structure, fracture fillings/cavity fillings and pisolith enclaving clay at the core (Fig. 1 a–d). At places, pisoliths of clay of varied size are cemented by goethite giving an intimate interlocking of clay and goethite to a scale of <10 μm. The observations reveal that the interlocking of goethite and clay ...
