Abstract Ilmenite is the prime mineral used for the production of titania-rich slag and ferrotitanium alloy throughout the globe. In the current research, a 30 kW DC extended arc plasma reactor is employed for the aluminothermic reduction of ilmenite into ferrotitanium. For low-temperature operation, flux is added targeting low melting slag …
Ilmenite, as the main titanium source in practice, is of critical importance in meeting the pressing needs of various titanium associated fields. Herein, a review of …
Ilmenite (FeTiO 3), a waste of the titania production industry, is proposed as a potential candidate for visible-light-driven photocatalysis due to its narrow band gap (E g = 2.01–2.90 eV). However, to date, its photocatalytic performance has been very poor, even significantly lower than TiO 2 (E g = 3.2 eV) due to its high iron content. Herein we report …

Ilmenite is the primary feedstock for the manufacturing of titanium goods, however it needs to be refined before the usage. Becher is an eco-friendly process for refining ilmenite by rusting metallic iron from reduced ilmenite to separate iron and TiO 2, and NH 4 Cl is the commonly utilized solvent in this method. In the current study, the …
Ilmenite, which is the main source for titanium, existed in the stripes within magnetite; it got pulverized first during milling and remained as relatively coarse particles of magnetite. A grinding time of 15 min was determined as optimum for the grinding conditions of this study, based on the degree of liberation, the grade, and recovery of ...

Before the tu rn of the centu ry the very large ilmenite ore reserves within the Storgangen ilmenite norite body were known (e.g.Vogt1887, 1892, Kolderup 1896). After about ten years of pioneering research on utilising the Ti contents of the ilmenite, the chemists Drs. P. Farup and G. Jebsen suc ceeded in 191 6 in developing an industrial ...
3.2 Chloride-Ilmenite Process In the chloride-ilmenite process, ilmenite, which, even at high grade, has a substantially lower TiO 2 content (approximately 65%) than rutile, is converted to TiCl 4. The ilmenite ore used in the process contains a much larger amount of iron than the other ores (i.e., rutile or high-grade ilmenite) used to produce ...
for processing titanium-containing raw materials. The fundamentals of the ammonium fluoride method for processing titanium-containing raw materials were laid by Svendsen and described in his patents [23,24]. The methods consist of heating and fluorination of rutile or ilmenite in a mixture with ammonium fluoride or bifluoride, …
High-quality ilmenite, leucoxene, and rutile can be directly used as feedstock for the production of TiO 2 pigments and titanium metal (Gázquez et al., 2014, Perks and Mudd, 2019). However, lower quality ilmenite requires prior processing to produce titanium slag or synthetic rutile (Perks and Mudd, 2019). Consequently, rutile is the most ...
After decades of development of the vanadium titanomagnetite (VTM) ore in the Panzhihua district changes have taken place to the ore characteristics. In addition, preliminary research carried out in this area mainly focused on the separation and extraction of iron resources and lacked a systematic research focus on the process mineralogy of …
The results of ilmenite flotation using NaOL as a function of pH are shown in Fig. 2. As seen in Fig. 2, ilmenite exhibited a relative good flotability at pH between 4 and 10, and the flotation recovery reached the highest recovery (74.74%) at pH 5.5 with H 2 SO 4 as a regulator. Thus, pH 5.5 was chosen as an optimum pH value, and is selected ...
The fine ilmenite material finer than 0.045 mm at the Pang Zhi Hua Ilmenite Processing Plant was discarded for the lack of efficient processing equipment and method. The total recovery of ilmenite ...
The heavy minerals were naturally concentrated in Pliocene-age shoreline beach and dune sands by wind and wave action. The key heavy minerals in these deposits include ilmenite, rutile, zircon, and leucoxene (mixture of altered titanium bearing minerals). In 1996, mining and processing of the heavy mineral sands began from the Old Hickory deposit.
It focuses on ilmenite as a major source of titanium and some effective methods for producing titanium through extractive metallurgy processes and presents a critical view of the opportunities and challenges. ...

SR is used as feed stock for the production of titanium dioxide pigment via chlorination-oxidation process, and titanium metal via magnesiothermic reduction process, or directly used as welding electrode covering [1, …
Another important parameter for the processing of ilmenite is the agitating speed. When the agitating speed is increased from 100 to 500 rpm in 100 rpm increments, the maximum percentage of titanium and iron was leached at 400 rpm and remained the same at 500 rpm. The temperature was found to affect the dissolution of ilmenite and the ...
