1. Introduction. Ilmenite (FeTiO 3) ore consists mainly of titanium dioxide (TiO 2) and iron oxide, with small amounts of other oxides.However, iron oxide is one of the main impurities that affect the commercial value of ilmenite. Ilmenite is the main feedstock in the Becher process that is used to produce synthetic rutile (SR), a high-grade titanium product …
Ilmenite smelting is a reduction process in which the FeO in ilmenite is reduced to Fe, giving a titanium-rich slag on top of pure pig iron [1]. Slags analysis is of great importance in ilmenite ...

In the actual production, in order to ensure the high grade of iron concentrate, the two-stage grinding step separation process is often used. However, after two-stage grinding, ilmenite overgrinding is inevitable in iron dressing tailings, resulting in a substantial increase in the content of ultra-fine ilmenite (particle size less than 38 μ m).
Apollo astronauts found abundant ilmenite in lunar rocks and the lunar regolith. Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3. …
The reaction mechanism of metallic iron in corrosion process was proposed. The results showed that corrosion temperature played a key role in determining the transformation of metallic iron in reduced ilmenite during corrosion process. Under suitable corrosion conditions, Fe-bearing mineral in reduced ilmenite could be converted to amorphous ...
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 used to manufacture titanium dioxide, TiO 2, an important pigment, whiting, and polishing abrasive. Heavy Mineral Sand ...
Basic reactions in ilmenite smelting are: Reduction of FeO from slag. FeO + C → Fe + CO. Partial reduction of TiO 2 from slag. TiO 2 + 1/2 C → TiO 1.5 + 1/2 CO. Watch the video below to see the production process at Tizir Titanium & …
To study that challenge, Iron Range Resources allocated a $300,000 grant in February of 2016. It was matched by $300,000 from the University of Minnesota to fund a pilot-scale demonstration of ilmenite processing technology. Researchers also collaborated with Process Research Ortech, near Toronto, to develop a process.
Ilmenite by itself is not a profitable iron ore as the titanium inhibits the smelting process. Ilmenite, hematite and corundum all have similar structures and belong to a more or less informal group called the Hematite Group with a general formula of A 2 O 3. The structure is composed of alternating layers of cations and oxygens.

A hydrometallurgical process is provided for producing pigment-grade TiO2 from an ilmenite ore concentrate containing by weight a relatively high magnesium content ranging up to about 10 %, an iron content of at least about 15 % and a titanium dioxide content of at least about 25 %. The concentrate is selectively leached with hydrochloric acid at a concentration ranging up to about …
The main problem of processing of ores with a high content of titanium oxides is refractory slag based on TiO2, which makes it difficult to melt. The methods of processing of titanomagnetite and ilmenite ores were analyzed. It is shown that the existing scheme of processing does not meet the requirements of complex use of materials. The paper presents the results of …
Ilmenite is converted into titanium dioxide via the sulphate process. Sulphate process plants must utilise low-vanadi um ilmenite, as vanadium is a penalty el ement.
The current work focuses on chemical and photochemical processing of iron-containing mineral dust particles in the presence of nitric acid, and an organic pollutant dimethyl sulfide under atmospherically relevant conditions. More importantly, ilmenite (FeTiO3) is evaluated as a proxy for the iron-containing mineral dust.

In our previous publication, we published a simple, low-cost, and environmentally friendly process for the breaking down of the ilmenite lattice using rotary autoclaving, separation of titanium and iron components, and the conversion of the titanium component to amorphous TiO 2 and phase-specific titanium dioxide nanorods. Here, the separated iron component was …
Rutile is easy to process to titanium metal or TiO2 pigment by the chlorination method while ilmenite is more complicated because of its high iron content. Since the world reserves of titanium are 90% in the form of ilmenite and only 10% in the form of rutile, the treatment of ilmenite is evidently an important question in metallurgy [1,2].
