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.

Titanium or vanadium metals or their alloys are important industrial metals/alloys. Because these resources are in short supply, the investigation of potential titaniferous-vanadiferous deposits needs special attention to bridge the supply-demand gap. The study integrates geological, geochemical, remote sensing, and geophysical data for assessing the …

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 ...

Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation technologies. In particular, …

Blåfjell mine, Rogaland, Norway. The sample is from an abandoned mine, but not far from Blåfjell is a working Tellenes mine (picture below). Width of sample 13 cm. Another aspect that separates it from magnetite is the crystal structure. Magnetite is an isometric mineral, it forms double pyramids (octahedrons) just like diamond.

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.

ilmenite, iron-black, heavy, metallic oxide mineral, composed of iron and titanium oxide (FeTiO 3 ), that is used as the major source of titanium. It forms solid-solution series with …

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.

Ilmenite crystallizes in the trigonal system. The ilmenite crystal structure consists of an ordered derivative of the corundum structure; in corundum all cations are identical but in ilmenite Fe 2+ and Ti 4+ ions occupy alternating layers perpendicular to the trigonal c axis. Containing high spin ferrous centers, ilmenite is paramagnetic.
