In this study, TiO2 nanoparticles have been obtained from low-grade ilmenite ore via two consecutive acid digestion and solvent extraction processes. The as-extracted TiO2 (Anatase phase) product was characterized using techniques such as XRD, XRF, FESEM, FTIR and BET surface area. Diluted sulfuric acid and D2EHPA (bis-(2-ethyl-hexyl) phosphoric acid) were …
Lithium brine ponds: concentrating and precipitating impurities from geological lithium brines via evaporation ponds.A highly concentrated lithium solution is subsequently refined and converted into lithium carbonate or hydroxide. These low-cost operations are ideal for the convergence of rich lithium brines and arid climates, such as South America's 'lithium triangle.'
menite concentrate was lower than that of pure ilmenite. It is known that manganese oxide could inhibit the reduction of the ilmenite and lead a lower reduction degree.22) There-fore, it is considered that the lower reduction rate of Bama ilmenite is due to the manganese oxide contained as an im-purity.
An extraction efficiency of 97% total titanium was obtained by 1.5 M TBP in kerosene from initial 10g/L ilmenite leach liquor at 25 ± 2 o C in a single extraction stage.
In the meanwhile outdated, but still in use 8th edition of the mineral systematics according to Strunz, the ilmenite belonged to the mineral class of "oxides and hydroxides" and there to the department of "oxides with the molar ratio of metal: oxygen = 2: 3", where he named the "Ilmenite group" with the system no. IV / C.05 and the other ...

ilmenite the key material discussed in this review contains iron as the main impurity along with other impurities includ-ing SiO 2, MnO etc. as discussed in Sect. 2. Presence of such impurities also contribute to enhance the activity of Ti based materials especially in photocatalysis. Hence, it is signicant to study about ilmenite which is the ...
The Ti extraction of ball-milled ilmenite slightly increased from 50 wt% (9.4% Ti) to 60 wt% (10.5% Ti) and reached a maximum Ti extraction of 29.8% at 70 wt%. This is ascribed to the increase in the rate of Ti extraction from the cake containing potassium titanate (K 4 Ti 3 O 8) into the leachate (Eq. 8).
For several decades, the metallurgical industry and the research community worldwide have been challenged to develop energy-efficient and low-cost titanium production processes. The expensive and energy-consuming …
The extraction results from ilmenite rock using the hydrometallurgical method produce TiO 2 Anatase phase raw material with a purity level of 99.3%. It is concluded that this study has succeeded in understanding the identification and analysis of the composition of ilmenite stones from Pandeglang, Indonesia. ... Titanium is a metal that is very ...
The commercial processes to extract iron from ilmenite (FeTiO3) essentially include energy-intensive methods, such as high-temperature reduction smelting or preoxidation, coupled with reduction by carbon. However, due to altered mineralogy of ilmenite caused by weathering at sea coast, the reduction of iron remains incomplete in either of these processes, …

Vanadium titanomagnetite (VTM) is an important mineral for developing titanium resources, but the comprehensive recovery of ilmenite separation is extremely poor, resulting in the low-efficiency utilization of titanium resources. Here, the separation of ilmenite from VTM ore is studied by combining magnetic separation and flotation technologies. In particular, the …
