The ilmenite-hematite (FeTiO 3-Fe 2 O 3) solid solution (Ilm ss) commonly occurs in layered intrusions (Harrison et al. 2000).Ilm ss tends to experience subsolidus re-equilibration and phase transformation during different T-f O 2 cooling paths, forming hematite and/or magnetite exsolution and magnetite-rutile intergrowths in ilmenite …

The vast majority of ilmenite are produced from heavy mineral (HM) rich sand mines, such as Moma in Mozambique and Kwale in Kenya, and titanium-rich igneous and metamorphic hard-rock mines, like Tellnes in Norway and Panzihua in Sichuan China. Our Roper River Ilmenite Mine is different and unique as ore is expressed as reddish and brownish ...

The positive correlations of Ni and Cr between magnetite and ilmenite and large content variations indicate extensive fractional crystallization of the Fe–Ti oxides (Fig. 7). Both Sr and REEs are compatible in apatite but incompatible in magnetite and ilmenite, and thus apatite fractionation would cause Sr and REEs depletion.

The mine contains the titanium minerals ilmenite, rutile and zircon, which are used as feedstock to produce titanium dioxide pigment. It started production of heavy mineral concentrate (HMC) containing these three minerals in April 2007. It produced 1,201,100t of HMC and shipped approximately 853,100t of finished products in 2020.

Titanian magnetite consists of magnetite as a host crystal that contains exsolution lamellae of ilmenite, ulvöspinel and/or spinel. Commonly, ilmenite is derived from initially exsolved ulvöspinel (Sect. 7.2). The Fe-Ti oxide ore is typically hosted by anorthosite, whereby two different geological settings can be distinguished:

Situated ∼360km north of Cape Town on the west coast of South Africa, the Tormin Mineral Sands Operation consists of a number of high-grade placer beach and strandline mineral sands deposits hosting some of the richest grades in the world of naturally occurring zircon, ilmenite, rutile, magnetite and garnet.

The magnetite- and ilmenite-series granite classification is based on magnetite contents of granitic rocks, and the boundary of the contents is 0.1 modal percent (Ishihara, 1977).

Cenozoic–Mesozoic plutonic zones are classified by (1) the redox state (magnetite/ilmenite series), and (2) average bulk composition (granodiorite/granite). The granodioritic magnetite series occur with fairly abundant gabbro and diorite in the back-arc of island arcs (Greentuff Belt) and intercontinental rapture zones (Yangtze Block).
