Ilmenite has been identified in lunar rocks, connecting this earthly mineral to extraterrestrial geology. Its presence on the moon has sparked interest in its potential role in future space exploration. In 2022, the total global production volume of ilmenite amounted to 8.9 million metric tons of titanium dioxide equivalent.

1. Introduction. Ilmenite and rutile are the main sources of titanium with 90% of commercial TiO 2 coming from ilmenite and 10% from rutile. Hard-rock deposits associated with Proterozoic anorthosites provide 30% of ilmenite while the remaining 70%, and all rutile, comes from placers (Gambogi, 2010).Despite an abundance of world resource for Ti ores, the …

Ilmenite is an iron titanium oxide. It is the principal ore of titanium. It is black (or dark gray) and has a metallic luster. It is usually weakly magnetic. The mineral itself is actually not magnetic, but it is often intergrown with magnetite, which very strongly responds to the magnetic force. You can use a hand-held magnet to test sand grains.

[1–3], including hard rock and sand deposits. Because the chemical composition of ilmenite is unstable, flotation processing characteristics of ilmenite varies from one ore type to another. Figure 25.1 shows the flotation of ilmenite from different ore types at different pH levels using 200 g/t of oleic acid.

Most ilmenite is recovered from heavy mineral sands ore deposits, where the mineral is concentrated as a placer deposit and weathering reduces its iron content, increasing the percentage of titanium. However, ilmenite can also be recovered from "hard rock" titanium ore sources, such as ultramafic to mafic layered intrusions or anorthosite massifs.The ilmenite in …
