As examples, the ilmenite tailings case study presented in this paper shows how advances in technology have allowed for increased recovery of -45 μm ilmenite by utilizing a multi-stage SLon® wet magnetic separator circuit equating to an additional 30 000 tons of ilmenite produced per year.
Ilmenite disseminated grain size is relatively fine, and it must be finely ground to fully separate ilmenite from gangue and then produce fine-grained minerals, which deteriorates flotation. A novel method using buoyant carriers to improve the recovery of fine ilmenite in froth flotation was introduced in this study. Hydrophobized glass bubbles (HGB) as carrier materials …
Modal percent of ilmenite within these meteorites ranges from 3.1% to 5.1% (Table 1). Ilmenite in these samples contain very low concentrations of MgO with a range from 0.02 to 0.24 wt. %. Baddeleyite: Occurs in association with ulvospinels, ilmenite and troilite, and is typically 20 to 40 µm in size.
A novel approach for Ta and Nb extraction consisting of the pre-treatment of a coltan-bearing ore with an ammonium bifluoride sub-molten salt and subsequent acid leaching has been studied. The effects from ore granulometry, ammonium bifluoride (ABF) to ore mass ratio, temperature and duration of fluorination on the degree of Ta and Nb extraction were examined.

The purpose was to use HTGR nuclear heat for the substitution of fossil fuels to ... gas-cooled test reactor (referred to as HTR-10). Basic design of HTR-10 was completed in 1994[4], and the
Titanium mineral resources of the Western U.S.—an update By Eric R. Force1 with a section on Ione Basin, California By Eric R. Force1 and Scott Creely2 Open-File Report 00-442 2000 Notes from the "Titanium-Mineral Resources of the U.S." short
Recovery capacities at 100° F rise equal: for non-simultaneous element operation = 4.1 gal. x kW of one element; for simultaneous element operation = 4.1 gal. x 2/3 kW of both elements. For other rises multiply element kW as previously explained by 410 and divide by temperature rise. Full load current for single phase = total watts/voltage.

Dundas IImenite Project. The Board believes that Dundas is a world class project, with work to date demonstrating that it has the potential to be advanced into production in the lowest quartile of production costs test. The Company is …
Ilmenite has a lower TiO 2 content than natural rutile but has the most abundant reserves of all titanium minerals. [1,2,3] Naturally occurring ilmenite can be classified into primary and secondary ilmenite according to its genesis and subsequent weathering history.Primary ilmenite is found in igneous rock deposits and has a relatively low TiO 2 content (30 to 50 wt pct).
The existing fatty acid collectors generally have problems of poor separation performance and low recovery in the strongly acidic pulp of the flotation of ilmenite concentrate. In this study, a surfactant, dodecyl dimethyl betaine (BS-12), was introduced to ...
The reason why HTR-CTO achieves better recovery results even the rank is inaccuracy is that the Hankel transformation enriches the structure of the core tensor mode matrix, hence, more information can be used to complete the recovery task.

concentrate, and ilmenite concentrate. The ilmenite concentrate was found to have the following chemical assay: 38.9% TiO2, 31.1% Total Fe, 6.4% SiO2, 7.6% MgO, and 0.32% V2O5 with an estimated weight recovery of 45.5% and a TiO2 recovery of 71.3%. The beneficiation process
Table 1 presents basic information about ilmenite properties (rutile properties are also provided for a comparison), and Fig. 2 shows the crystal structure of ilmenite. The theoretical TiO 2 content in ilmenite is 52.7% and the specific gravity of ilmenite is high (ilmenite is considered to be a heavy mineral with the specific gravity of about 5). Fig. 2 shows that ilmenite crystallizes …
How to avoid effect of MFA to discuss temperature dependency of HTR of TW. As is well known, MFA in the secondary cell wall is the intrinsic property of specimen, which often affects dimensional stability and mechanical strength (Barnett and Bonham 2004; Donaldson 2008), as well as HTR behaviors (Tanaka et al. 2014, 2015; Sujan et al. 2015).What must be …
Relatively coarse grain size in comparison with many competing products (with D50 148µm). Ilmenite is a naturally occurring mineral, with the chemical formula FeTiO3. It has a titanium dioxide (TiO2) content between 45% and 65% and generally pigment manufacturers pay feedstock suppliers on the basis of TiO2 content.
titanaugite with the grain size bellow 10 µm has serious effect on the recovery of ilmenite.The results of DLVO theoretical calculations indicate that the total acting energy between the titanaugite and ilmenite particles at pH 5.9 is negative, showing as ...
Ilmenite (FeTiO3) is black and opaque when fresh, but has typically undergone some weathering and iron removal, so TiO2 contents are between 45 and 65%. Leucoxene is the name given to highly altered ilmenite. Grains are …
The average particle size of ilmenite ore was less than 100 μm. The composition of raw ilmenite was investigated by X-ray fluorescence spectroscopy (XRF; ZSX Primus II, Rigaku, Japan), and X-ray ...
Either ilmenite concentrate (45 to 65 pct TiO 2) or Ti-containing slag (79 to 86 pct TiO 2) can be used in this method. Further, different parameters influence the process efficiency and recovery such as particle size, acid concentration, temperature, reaction time, acid-to-solid ratio, and agitating rate.[24,25,26,27]
Hygrothermal recovery (HTR), the dimensional changes in wood induced by hygrothermal treatment, was investigated using both compression and normal wood of sugi (Cryptomeria japonica). The elastic released strain of growth stress was measured on living tree surfaces; subsequently, the specimens were taken from the same position to measure HTR. …
