Reduction of a titano magnetite ore has been executed at temperature ranging from 800 to 1200 °C using methane contents between 10 and 30 vol% in the hydrogen–methane gas mixture. ... with the necessary flux additions to separate a titanium oxide-rich slag and a vanadium containing iron liquid phase both of which can be …
To overcome this, a passivation layer is required. A stable form of magnetic titanium dioxide has now been patented by this group. 2. ExperimentalThe preparation of the magnetic photocatalyst particles entailed the coating of a magnetic iron oxide core with a layer of photoactive titanium dioxide. These samples are referred to as TiO 2 /Fe …
Titanium dioxide (TiO2, also known as titanium (IV) oxide or titania) is the naturally occurring oxide of titanium. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. Generally, it is produced from ilmenite, rutile, and anatase. It has a wide range of applications, from paint to sunscreen lotion to food ...

The oxygen to titanium and titanium/silicon ratio exceeded the expected one (2.0 considering only SiO 2 and/or TiO 2, as Fe 3 O 4 core is almost undetectable) for nearly all analyzed samples, reaching 2.5, 2.0 and 2.6 for ST01: bare on magnetic core, modified with 0.05 mol% Pt on magnetite and modified with 0.05 mol% Pt and 0.1 mol% …
After oxidation in the mineral sand, the α-hematite phase was identified. The result of the reduction was the obtaining of elemental iron and titanium carbide (khamrabaevite). Finally, the reduced ore was leached with an acid solution (3% HCl for 48 h), completely dissolving iron and vanadium, while titanium dissolved 76.92% of its original ...
This indicates that the sample of titanomagnetite iron sand of this extract has ferromagnetic properties.When the magnetic field intensity of H is increased to reach H = 1 Tesla, the value of M...
The iron oxide was basically dissolved with iron-titanium oxide when the basicity was 1.2. The reaction between TiO 2 and CaO can explain the relationship between iron oxide and titanium iron oxide. Fe 2 O 3 produced by the oxidation of magnetite combines with TiO 2 and CaO to generate a titanium iron solid solution and perovskite.
2.1. Materials. In this experiment, vanadium-titanium magnetite concentrate from Wuling, Xinjiang was used as raw material, and its chemical composition is depicted in Table 1.It can be observed from Table 1 that the main valuable elements in the raw iron concentrate are Fe, V and Ti, with the mass fractions of TFe, TiO 2 and V 2 …

A typically low-grade titanium sand was first ground and then processed by low-intensity magnetic separation (LMS) and high gradient magnetic separation …
their final use. Generally, ilmenite 1 contains more than 58% titanium oxide and ilmenite 2 contains 54% titanium oxide. All of these separations generate rejects that will be recycled in the separation process. The non-magnetic product (WHNM) is then treated to produce zircon, rutile and leucoxene concentrates.

South African vanadium–titanium magnetite is a complex mineral resource rich in iron, vanadium, titanium, and chromium [1,2,3].Its ore composition is composed of more than 20 elements [4,5,6].It is the most complex ore of its type in the world and contains more than 10 valuable elements, so it has a very important integrated utilization …
Efficacious oil-water separation has become a global challenge owing to regular oil spillage accidents and escalating industrial oily wastewater. In this study, we synthesized titanium dioxide and magnetite iron oxide nanoparticles to use as a precursor for the production of the nanocomposites. Hydrophobic nanocomposites were fabricated using polyurethane, …

Magnetic separation showed that the finer the particle and the higher the magnetic intensity, the higher the derived iron and titania.s The process has also successfully increased the TiO 2 content more than 5 times, from 0.325 to 1.67%. Keywords: iron sand, particle size, magnetic separation, titanium oxide.
The formation of Ti(C,N) would result in slag ing, high viscosity of slag, difficulty in slag–iron separation and low desulphurization, which seriously deteriorates the running conditions of BF. Aiming to improve the operation conditions of BF, it is necessary to add ordinary iron ore to decrease the titanium oxide content in slag [18 ...
