Titanium is not free in nature and must be extracted by several processes. The titanium ores that are mined are ilmenite [mixed oxide of titanium and iron (FeTiO 3 or FeO·TiO 2)], rutile, anatase, and brookite, which have the same formula (titanium dioxide TiO 2) and different crystalline structures.Other less common titanium oxide-bearing minerals are …

There are more than 140 minerals with a titanium content greater than 1%, but most of them have no industrial use. Two types of ore that have been widely mined and utilised are rutile and ilmenite. This article introduces the nature, structure, application areas, separation processes and equipment of rutile and ilmenite.
To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.
Monazite is a RE–thorium phosphate, in which high content of a naturally occurring radioactive element presents a negative aspect of mining and processing (Kul et al., 2008). As a result, it is mined as heavy-mineral sand from Aeolian beach and recovered as a by-product during processing of ilmenite, rutile, zircon and cassiterite.

The apatite-ilmenite ore was of an igneous origin. This ore contained apatite and ilmenite as a major valuable mineral with feldspar, olivine, dolomite, pyroxene and magnetite as gangue minerals. Ilmenite in the ore was present as magnetic ilmenite. The rutile ore was composed of rutile with quartz, dolomite, feldspar and mica as gangue minerals.
High-quality ilmenite, leucoxene, and rutile can be directly used as feedstock for the production of TiO 2 pigments and titanium metal (Gázquez et al., 2014, Perks and Mudd, …

"At present we obtain 40,000 tons of ilmenite each year. This fetches $240 per ton on the international market. At present approximately 40,000 tons ilmenite, 25000 tons rutile and 1200 tons zircon are produced," said Mr. Gnaneswaran, the Acting General Manager of the Pulmoddai Ilmenite Factory, who has been in service there for 30 years.
The flotation processing characteristics of pervoskite, ilmenite and rutile from igneous and sedimentary ores were examined in the course of developing a commercial treatment process. Flotability of these minerals was found to be strongly influenced by a) flotation pH, b) pulp treatment before flotation, and c) type of collector.
Dry Mining of Ilmenite and Rutile. Dry mining meanwhile is carried out with conventional earth moving plant including excavators, scrapers, loaders and bulldozers. Like wet dredging, the sediments from dry mining also need to be concentrated this is the same as the above process but is done without water in the spiral concentrator.
This report presents a newly developed process called the Magpie process, which enables the production of high-grade synthetic rutile (over 95% TiO2) from low grade ilmenite …
Extraction of vanadium from titanoferrous magnetite: mineral processing and enrichment methods. In Vanadium, 2021. 4.2.5 Ilmenite. Granular ilmenite is the main mineral used for the recovery of titanium. Granular ilmenite is often associated with titanomagnetite, or distributed in silicate mineral grains, and forms via automorphism and semiautomorphism processes.
1. Gravity separation In the rutile ore beneficiation process, there are two main uses for gravity separation: one is for the sorting of rutile ore with coarser grain size, another one is for the tailing work of fine-grain rutile, generally used for pre-treatment before flotation, which can effectively remove the slime and can remove part of the gangue.

Titanium processing - Extraction, Refining, Alloying: The production of titanium metal accounts for only 5 percent of annual titanium mineral consumption; the rest goes to the titanium pigment industry. Pigments are produced using either a sulfate process or a more environmentally acceptable carbo-chlorination process (described below) that converts TiO2 into TiCl4.
