Since the start-up of the company in 1986, ETI has used a state-of-the-art process smelting ilmenite to produce titanium slag and high purity pig iron. It is the only plant in Europe using such process and only one of 8 plants (outside China) worldwide. The plant is unique as the production involves a two-stage process: Prereduction in a rotary ...

We investigated the carbothermic reduction process of ilmenite ore at 1873 K with flux addition. Without flux, the pseudobrookite phase with a high melting temperature was precipitated during ...

Natural rutile was the feedstock of choice at the early years of the Kroll process, but nowadays it comes in limited supply. Titanium dioxide slags are produced by reduction smelting of ilmenite in electric arc furnaces. The slag grade (sulfate or chloride) depends essentially on the quality of the ore or concentrate fed to the slag furnaces.

Setting up a state-of-the-art ilmenite ore processing plant with the right equipment and machinery can significantly impact your mining operations. It ensures efficient processing, higher yields ...

Ilmenite can also be converted to a more pure titanium dioxide product using the Becher process. This process consists of high-temperature exposure to oxygen in air to convert ilmenite to pseudobrookite: 4FeTiO 3 + O 2 = 2Fe 2 O 3 TiO 2 + 2TiO 2. The oxidation process oxidizes the iron and allows it to form a separate iron oxide phase.

A hydrometallurgical process is provided for producing pigment grade TiO 2 from titaniferous mineral ores, and in particular from ilmenite ore. The ore is leached with a hydrochloric acid, preferably a recycled solution at high hydrochloric acid concentration, to form a leachate containing titanium and iron chloride and a residue. The leachate may be …

Ilmenite ore is one of the main sources of titanium minerals. Many methods such as, sulfate processing is being applied for the production of synthetic rutile from ilmenite (Mao et al., 2021), however, due to processing cost and environmental impact for commercial exploitation only certain of the methods were useful for commercial …

Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3. 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 …

Chlorination process is a clean and efficient way to manufacture of titanium dioxide pigment. However, the limited natural rutile promotes the investigation on the upgrading of ilmenite ore into ...

Besides, many studies showed that the reactivity of ilmenite ore OC would be significantly enhanced after a pre-activation by subjecting the pristine OC to multiple redox cycles [24, 29, 30, 37]. During such an activation process, the ilmenite ore should be reduced by the fuels such as CO, H 2, CH 4, etc., and oxidized by the oxygen for many ...

In the Austpac process, ilmenite ore is roasted to selectively magnetise the ilmenite, and removed the gangue minerals by magnetic separation, followed by a hydrochloric acid leaching process [4]. Oxidation and reduction of ilmentie followed by hydrochloric acid leaching is utilized by Murso process [5]. In the above mentioned …

Titanium processing, the extraction of titanium from its ores and the preparation of titanium alloys or compounds. ... Titanium ore was first discovered in 1791 in Cornish beach sands by an English clergyman, ... (TiO 2), and ilmenite (FeTiO 3), which contains 50 to 65 percent TiO 2. A third mineral, leucoxene, is an alteration of ilmenite from ...

1% rutile are economic and ilmenite sand deposits may be mined at approximately 5% ilmenite. In ilmenite hard-rock deposits, however,the ore hasto be mined,crushed and the ilmenite separated out by an expensive separation process; therefore ore-grade requirements will be high. The signifi­ cant differencesbetween majorTi ore-typesin terms …
