Ilmenite has the ideal composition of FeTiO 3 and a trigonal corundum-type crystal structure [9]. Massive ilmenite is found in lenses and layers, as well as disseminated patterns within igneous anorthosite and gabbro rock complexes. At temperatures higher than about 700°C, ilmenite becomes miscible with hematite (Fe 2 O 3) and vice versa [9].
