Occurrence and distribution of titanium ore in nature. Titanium is the 9th most abundant element in the Earth's crust, occurring primarily in the form of minerals known as titanium ores. The most common titanium minerals are ilmenite (FeTiO3), rutile (TiO2), and leucoxene (a weathered form of ilmenite). These minerals are widely distributed in nature, …
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 …
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 …
Pitfield represents a newly recognised type of stratabound sedimentary rock-hosted titanium deposit, unlike the more common beach sand and hard-rock types of titanium deposits found globally. Initial petrography work confirms the presence of ilmenite, a titanium-iron oxide mineral, which is highly valued as a source for titanium oxide and which ...

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.

Naturally available ilmenite mineral is being used as a starting material to produce titanium based products that have wide applications. Transformation of ilmenite to different titanium based materials by strong and weak acid, and base digestion, is discussed. Effects of temperature, concentration of acid/base, reaction time on dissolution of ilmenite are …

Ilmenite and rutile are currently the most important titanium-bearing minerals, although anatase may be important in the future. Both ilmenite and rutile occur in hard-rock and placer …
Although ilmenite and rutile are extensively used to extract TiO2 at the industrial level, through the sulphate and chloride processes, they can also be recognized to possess the potential to be employed as the raw material to synthesize other titanium compounds as well. The Pulmoddai mineral sand deposit in Sri Lanka is considered as a valuable resource containing …
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.

By retrogradation about 95 per cent of the TiO2-content occurs as rutile and about fi ve per cent as ilmenite. Liberation of rutile is a critical parameter. Processing may include grinding in a ...
[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.
