The Transformation of Lepidocrocite to Goethite
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 …

Mineralogical and thermal characteristics of synthetic Al-, Cr-, Mn-, Ni- and Ti-bearing goethites, synthesized via alkaline hydrolysis of metal-ferrihydrite gels, were investigated by powder X-ray diffraction and differential thermal analysis. Shifts in unit-cell dimensions were consistent with size of substituent metal ions and confirmed the incorporation of Al3+, Cr3+, …

Mining. Most iron ores mined today comprise the iron oxide minerals hematite, Fe 2 O 3 (70% Fe); goethite, Fe 2 O 3 s H 2 O, (63% Fe); limonite, a mixture of hydrated iron oxides (up to 60% Fe); and magnetite, Fe 3 O 4 (72% Fe). As with most iron ore mines throughout the world, all the major Australian iron ore mines are open cut.

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 ...
