A novel technology for the refinement of low-grade ilmenite concentrate

Hydrometallurgy, 2018
Abstract In this paper, the refinement of low-grade ilmenite concentrate was studied. It was found that by transforming in NaOH/NaNO3 molten salt, and then leaching in water and in dilute hydrochloric acid, the low-grade ilmenite concentrate containing 3.09 wt% Mg, 1.03 wt% Ca, 3.38 wt% Si and 1.54 wt% Al can be refined well, meanwhile the contents ...

Propagation of Solid-Phase Iron Reduction in a Layer of Ilmenite Concentrate

Steel in Translation, 2020
Processing of titanium-containing ores together with the extraction of all the major elements is currently an urgent problem for the usage of mineral products. It is shown that none of the existing processing schemes allows the simultaneous extraction of all the major useful elements such as iron, titanium and vanadium from titanium-containing iron ...

SHS/PHIP of ceramic composites using ilmenite concentrate

Journal of Alloys and Compounds, 2010
Self-propagating high-temperature synthesis (SHS) process in the mixture of ilmenite, boron carbide and aluminum combined with a pseudo hot isostatic pressing (PHIP) is used in this research to produce a compact multi-ceramic composite Al2O3/TiB2/TiC with Fe as a binder. Several tests were performed to identify the optimum partial weight percent of the

Reduction of Ilmenite Concentrates By Methanecontaining Gas: Part I. Effects of Ilmenite Composition, Temperature and Gas Composition

Canadian Metallurgical Quarterly, 2001
AbstractReduction of ilmenite concentrates by CH4-H2-Ar gas mixtures was investigated in a laboratory fixed bed reactor in the temperature range of 850-1350 °C. Three ilmenite concentrates with different concentrations of TiO2 (55.6-71.5wt%) and iron oxides (Fetotal 14.5-28.2wt%) were examined.In the temperature range under investigation, iron oxides ...

Assessment of the technological possibility of joint processing of ilmenite and perovskite concentrates

Izvestiya. Ferrous Metallurgy
An urgent task facing the modern metallurgical industry is to increase the complexity of using mineral and technogenic raw materials by developing new technologies based on the principle of joint processing of raw materials from deposits that differ in the mineral composition of the ore component, for example, titanium-containing ores – ilmenite and ...

Effects of Pre-oxidation and Additive on Carbothermic Reduction of Ilmenite Concentrate

2017
The EAF smelting process of ilmenite concentrate consumes large amounts of energy. Semi-melting reduction can lower the reaction temperature and separate the iron and slag more thoroughly. However, this needs additives and pre-oxidation to promote the reaction. In this paper, the pre-oxidized ilmenite powders were reduced isothermally with graphite and

Energy consumption in the selective reduction of iron from ilmenite concentrate

Ferrous Metallurgy. Bulletin of Scientific , Technical and Economic Information
The main pyrometallurgical methods are single–stage electric melting and a two-stage method according to the “tubular furnace – melting unit” scheme. Both processing schemes involve the use of carbon as a reducing agent, which in turn leads to the formation of iron metal products and titanium oxide concentrate based on anosovite – Ti3O5.
