Pure titanium readily reacts with oxygen, and so much of the titanium found in nature appears as ore or "sponge", specifically rutile (TiO 2) or ilmenite (FeTiO 3 ). The Kroll process extracts TiO 2 from the ore through a reduction process in the presence of chlorine gas, which produces titanium tetrachloride (TiCl 4 ).
Titanium is a lightweight, strong and rust-resistant silver-white metal. Pure titanium is quite soft but titanium alloys are extremely strong (even stronger than steel and aluminium). Titanium has a very high melting point and is non-toxic. Titanium dioxide is one of the whitest, brightest substances known.

Titanium tetrachloride is an inorganic compound that is an important intermediate in the production of titanium metal and the pigment titanium dioxide. On contact with humid air, it forms opaque clouds of titanium dioxide (TiO 2) and hydrogen chloride (HCl). Early attempts to isolate titanium metal from titanium tetrachloride were unsuccessful. The …
The Kroll Process. Regardless of the final usage titanium must first be removed from its ore and turned into pure titanium. This is done by processing titanium oxide manufactured from either ilmenite or rutile though the Kroll process. The output is a titanium sponge which is purified, melted and alloyed with other metals.
Titanium dioxide is used as pigment material in the production of paints, paper, and many other products as well as a precursor material that is subsequently processed to produce titanium metal. Titanium tetrachloride is used as a precursor to titanium metal production via the Kroll process. The titanium is first processed at the …
Mining at the Moma titanium deposit. Titanium minerals at Moma are mined through dredging. The mining is carried out at Namalope flats, which was the first deposit mined. The dredges cut the ore at the surface level, causing the sand to slide into the dredge pond, which is nearly 800m-long, 300m-wide and 15m-deep.

Titanium sponge is of strategic importance owing to its usage in manufacturing titanium alloys for aerospace and defence applications. However, the extractive metallurgy of titanium, is complicated and cumbersome, resulting in high material costs and limitations on the use of titanium and its alloys.
In this study, the deoxidation process for off-grade titanium (Ti) sponge using magnesium (Mg) metal with a wire mesh strainer type of crucible was developed.
Consequently, the objective of this work was to analyze the CIP degradation efficiency, to identify the TPs generated by the activated persulfate oxidation process using a low-grade titanium ore under SL in a raceway reactor, and to obtain high efficiency degradation rates.
A magnetic separation process was investigated for the pre-concentration of low-grade vanadium-titanium magnetite ore. The results showed that 73.52% of feed ore were directly discarded for reducing the processing capacity of follow-up processing.
Titanium cannot be extracted by reducing the ore using carbon as a cheap reducing agent, like with iron. The problem is that titanium forms a carbide, TiC TiC, if it is heated with carbon, so you don't get the pure metal that you need. The presence of the carbide makes the metal very brittle.
Low-grade titanium scraps heavily contaminated by oxygen and iron are currently used for producing additive alloys (ferro-titanium) in the steel industry. In the near future, if the demand for titanium metal increases dramatically, there could be an oversupply of low-grade titanium scraps in the market.
Check out a complete guide on the TiO2 production process and the application of titanium dioxide in various industries.
Titanium is hard metal, non-magnetic and poor conductor of heat and electricity, in comparison to iron. In brief summary, titanium metal is processed through 4 major steps before the final finished shapes or product we see in day to day like. Extract and reduction of titanium ore into 'sponge' porous form.
Two novel, medium- to high-strength titanium alloys developed on the basis of CP-Titanium Grade 4 show excellent mechanical properties and, therefore, might be a possible alternative for Ti–6Al–4V for use in medical applications.

Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, TiO 2, an important pigment, whiting, and polishing abrasive.
More than 90 percent of the titanium minerals currently produced come from magmatic ilmenite deposits and from young shoreline placer deposits.
