Ilmenite is the primary ore of titanium metal, and its importance is only growing with time. As the global demand for titanium has increased rapidly over the past five years, with sponge shipments and exports of titanium scrap increasing 20% and 14% respectively between 2018 and 2019, the value of ilmenite has increased in response.
Read more about titanium ore mining and processing. Ilmenite concentrate (FeTiO 3) The primary raw material in the titanium dioxide production process is ilmenite concentrate (FeTiO3), produced by mining and processing. Ilmenite is an ore that, from a chemical perspective, is a mixture of oxides, the majority of which are titanium and iron …
The synthesis of TiO 2 from ilmenite ore commonly used the sulfate process and the chloride process. The sulfate process is less environmentally friendly, has excessive costs, and produces a lot ...
Ilmenite can be obtained from the black sand through various techniques utilized during the ore processing, including magnetic separation, floating separation and electrostatic separation [18,22], where the ore material is majorly composed of 75% ilmenite, 10% rutile, 8% zircon and trace amounts of other minerals [21,23].
The sulfate process which utilises ilmenite (FeTiO 3) as a raw material is well known and widely ... Ilmenite ore (a) Granular texture composed of anhedral grains of
Ilmenite is a significant mineral, which contains between 40% and 65% titanium dioxide. The other elements are either ferrous oxide or ferric oxide and sometimes small amounts of vanadium, magnesium, and/or manganese. Ilmenite's main sources are the heavy mineral sands (alluvial deposits) but are also commonly distributed in hard …
During this process, the essential condition for capturing the ilmenite from the ultrafine ore, key technology for obtaining an efficient preconcentration, and analysis of the ilmenite concentrates were investigated with theoretical descriptions, statistically designed experiments, and scanning electronic microscopy (SEM) detection, respectively.
The present work is devoted to the influence of combined microwave heating at a frequency of 2.45 GHz on the oxidation process of Vietnamese ilmenite ore. In oxidation by this method, the heating ...
Rutile (TiO 2) is a vital industrial material used in pigments and in many other valuable chemicals.A new production process to synthesize rutile from natural ilmenite ore and therefore overcome the environmental problems associated with conventional rutile extraction processes was developed.

However, the separation of Nb 2 O 5 and Ta 2 O 5 from the ore mineral and essentially from each other is a tedious and complex process as a result of their very close similar properties.
The dosage of (NH 4) 2 SO 4 required for high iron leaching is a critical factor for the roasting process. The effect of the ilmenite ore-to-(NH 4) 2 SO 4 mass ratio on the leaching efficiency of iron and titanium loss was investigated under the following optimal conditions: roasting temperature of 500 °C, roasting time of 210 min, and ...
The effect of microwave radiation upon the mineralogy and magnetic processing of a massive Norwegian ilmenite ore is presented. Short exposure to microwave radiation has been demonstrated to cause fractures within the ore matrix. Increased exposure to microwave radiation is shown to cause localised sample melting. The microwave treated …
Physicochemical and production properties of ilmenite concentrates are studied in order to determine the possibility of preparing from them the required titanium-containing industrial materials.

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 ...
Ore-microscopic examinations and microprobe analyses show the alteration of ilmenite by leaching to be a continuous process, proceeding from "leached ilmenite" through pseudorutile to leucoxene.
Australia has one of the largest resources of ilmenite and rutile forms of titanium oxide, and it is quite expected that Australia is facing the environmental impacts and health effects caused by the titanium ore extraction process (Haque et al., 2014; Jones, 2009; Reichl et al., 2016). The effect of this processing route on human health and ...
