In the development of a technological process for low-temperature (1000–1200 °C) processing of ilmenite or titanomagnetite concentrates to obtain pure TiO 2 are proposed. The advantage of this process over electric arc smelting in ore-thermal furnaces is the low temperature, which remains within the range of 1000–1200 °C, …

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].
Hydrometallurgical processing of ilmenite requires drastic leaching conditions basically with hot concentrated mineral acids. The main industrial route is the sulfate process. In the sulfate process, the ilmenite ore is dissolved in concentrated sulfuric acid solution (~ 85%) at a temperature of nearly 200 °C to prepare a titanyl sulfate solution.
The effects of some important leaching parameters such as leachant concentration, reaction temperature, and particle size on the extent of the ore dissolution were appraised for better prediction of the dissolution kinetics of the extraction process.

1. 1.1. Titanium is the ninth most abundant element making up about 0.6% of the Earth's crust (Das et al. 2013). Titanium is found in the form of ilmenite (40–80% TiO2) and mineral sand deposits, s...
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.
Overview In June 2024 Malaysia's Tin Ores exports accounted up to MYR2.11M and imports accounted up to MYR158M, resulting in a negative trade balance of MYR156M. Between June 2023 and June 2024 the exports of Malaysia's Tin Ores have decreased by MYR-483k (-18.6%) from MYR2.6M to MYR2.11M, while imports increased by …
It has been reported that high grade TiO 2 could be obtained from ilmenite ore through hydrometallurgical processing [15] [16][17]. In this case, iron content, which is a good doping candidate in ...
of Ore 18.3.1 Beneficiation and Upgrading of Ilmenite Ore Beneficiation of ilmenite ores typically includes the following process steps: crushing, grinding, sorting, sizing, gravity concentration, and mag-netic separation. The flowsheet for beneficiation of ilmenite ore is shown in Fig. 18.2 (Gueguin and Cardarelli 2007). The majority phases in an
Ilmenite, rutile, zircon, garnet, and monazite are the most common minerals found in HM deposits of commercial interest (Perks and Mudd 2019, 2020).Ilmenite (FeTiO 3), leucoxene (altered ilmenite: Fe 2 O 3.nTiO 2), and rutile (TiO 2) are critical titanium feedstock minerals, while zircon ((Zr,Hf)SiO 4)) is an important source of zirconia (ZrO …
The ilmenite ore used in this study was collected from Pantai Pasir Hitam, Langkawi …
To develop a flowsheet for separation of high grade titanium-rutile from ilmenite, that will meet market requirements. Rutile has a SG of 4.2, hardness 6.0 to 6.5 and is non-magnetic; while ilmenite has a SG of 4.5 to 5.0, hardness of 5.0 to 6.0, and is weakly magnetic.

The carbothermic smelting reduction process of ilmenite ore at high temperature was investigated by thermodynamic calculations in conjunction with smelting experiments. Based on thermodynamic calculations, conducting the smelting process at a higher temperature was recommended to achieve a larger amount of FeO reduction, i.e., …
Tin tailing, locally known in Malaysia as Amang, is the by-product of tin ore mineral acquisition, processing, and refinery. Hence, the focus was redirected in processing these residues, whereby valuable heavy minerals of Technologically Enhanced Naturally Occurring Radioactive Material (TENORM) were extracted ( Alnour et al., 2017 …
ilmenite (60% - 75% TiO2), leucoxene (76% - 90% TiO2) and rutile (95% TiO2) [7]. On the other hand, in alluvial sediments, ilmenite alters and Fe is partially leached in a conti nuous process going to pseudorutile (Fe2Ti3O9) and leucoxene [8]. For that reason, titanium and iron content in the ilmenite may vary significantly, as it can be
Authors in [18] explained that Abu Ghalaga ilmenite ore is not found as homogeneous grains but it is mainly hematite-ilmenite exsolution texture containing 36.78% TiO 2, 25.85% FeO, 29.86% Fe 2 O ...
