Mechanical activation processes on ilmenite concentrate were performed in three different energy levels. Iron powder as a reducing agent was added to ilmenite in the milling stage and the mechanically activated mixture was subjected to acid leaching. The leaching experiments were designed using the Taguchi method, and the optimum ranges were obtained. Furthermore, response …

While ilmenite has a nominal chemical formula of FeTiO3 (FeO.TiO2), assaying 52.7 wt% TiO2 and 47.3 wt% FeO (52.6 wt% Fe2O3), this ideal composition seldom occurs in …
The higher recovery of Ti was at 2 h of reaction time with 90 % recovery while recovery values decrease tremendously after 4 h and are constant at 6, 8 and 10 h of reaction. This trend was matched with previous works that reported the decreases of recovery value as time increases [ 9 – 11 ].

(including: PERMROL, CARPCO, HTR and HTP CORONA STAT separators). They are used to distinguish and extract magnetic, slightly magnetic and non-magnetic components present in the heavy fraction (Rutile, Ilmenite, Magnetite, Garnets, Zircon and Monazite) and to separate conducting (Rutile) from non-conducting (Zircon) minerals.
Effect size was measured using Hedges' g as it adjusts for sample size, thus providing an unbiased estimate of the standardised mean difference.44 Consistent with established recommendations for meta-analysis, effect sizes were interpreted as small (0.32), moderate (0.33–0.55) or large (>0.59).45 Heterogeneity was quantified using the I 2 ...
Rare Earths and Mineral Sands. The West Coast's mineral-rich, black sands are yielding encouraging levels of enrichment in rare earth elements, including within minerals not normally associated with them, such as epidote, ilmenite and zircon. NZIMMR's search for REEs is extending to mineral sands, and elsewhere in New Zealand.
The feedstock, as well as the bed material, has a wide size distribution in CFB boilers. As shown in Fig. 1, the flow pattern in the furnace is composed of the bubbling or turbulent bed formed by large particles at the bottom and the fast bed formed by fine particles in the freeboard . In the light of the gas–solid flow and heat transfer in ...

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 in the ...
The recovery of non-magnetic material is largely dependent upon a number of factors, including but not limited to dew point, ambient temperature, feed rate, mineral size distribution, specific ...
The Humphreys spiral was introduced in 1943, its first commercial use being on chrome-bearing sands. It is composed of a helical conduit of modified semicircular cross section. Feed pulp of between 15% and 45% solids by weight and in the size range from 3 mm to 75 µm is introduced at the top of the spiral.As it flows spirally downward, the particles stratify due to the combined effect of ...

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 …
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 were obtained by an ...

These deposits typically exhibit angular grains and greater size distribution and are often mixed with clays and oversize. Ilmenite is also mined from large hard rock deposits, where the rock has to be crushed to liberate prior to separating the mineral, which is typically of low TiO2 content.
