“…As mentioned above, ilmenite has benefit properties related to strong corrosion resistance and high mechanical strength due to its potential source for titanium, therefore, ilmenite separation from minerals is very substantial. Recently, flotation technique has commonly used for ilmenite recovery due to high ilmenite recovery achievement [6,7,8,9]. As already mentioned in the Introduction section, Hu [6] used sodium chlorite for ilmenite activation achieved ilmenite recovery of about 83%.…”

“…With regard to ilmenite recovery, several investigations used modified flotation technique to enhance the result [6,7,8,9]. Hu [6] applied sodium chlorite to oxidize Fe(II) ion to Fe(III) ion in sodium oleate system in order to improve ilmenite floatability, while Xiao [7] applied Al(III) ion in benzohydroxamide acid (BHA) to form Al-BHA complex yielding stronger effect on ilmenite floatability.…”

As similar method to Hu [6], Miao [8] applied Fenton to oxidize Fe(II) ion to Fe(III) ion in sodium oleate to enhance ilmenite floatability. Instead of Al(III) ion and benzohydroxamide acid used to improve ilmenite floatability [7], Yu [9] used Pb (II) ion and octyl hydroxamide acid (OHA) to increase ilmenite floatability.…”

“…Instead of flotation technique to improve ilmenite recovery, Yuan [10] used magnetic separation method based on interaction between ilmenite and magnetite yielding stronger magnetic properties of ilmenite from titanaugite. Generally, the previous investigations [6,7,8,9,10] used expensive chemicals to enhance ilmenite recovery. However, our present study does not need any chemical to obtain ilmenite from cassiterite.…”

This article aimed to separate ilmenite (FeTiO3) mineral from tin tailing applying a single splitter IRMS (Induced Roll Magnetic Separator). Ilmenite mineral is the substantial main source for TiO2. This work used air table middling for feeding. The mineral components of middling feeding from air table using grain counting analysis were found as follows: cassiterite (48.61%), ilmenite (21.36%), monazite (18.56%), pyrite (4.60%), zircon (5.85%), quartz (0.71%), anatase (0.27%), and tourmaline (0.02%), It was found that electrical current and opening of single splitter affected the degree of separation addressing to ilmenite recovery and ilmenite grade. The finding showed that current of 15 Ampere and single splitter with opening 4.25 cm yielded ilmenite recovery more than 74%. The high grade ilmenite (90.46 %) and recovery of 29.38% was obtained using 5 Ampere with single splitter opening of 1.0 cm. Up to date, the study on ilmenite separation from tailing only focused on the effect of current, however, the effect of single splitter magnetic separator to enhance ilmenite recovery from other paramagnetic minerals such as monazite, siderite, xenotime and tourmaline has not yet been reported.

“…Several direct and indirect techniques exist to measure the amount of sodium oleate adsorbed on mineral surfaces, but each have their own degree of accuracy, complexity, and cost. − Due to the simplicity, rapid implementation, low cost, as well as the eco-friendly character of the UV–vis spectroscopy technique, it is widely used and will continue to play a vital role in research . Adsorption studies using UV–vis spectroscopy require solution preparation, conditioning with the adsorbent, and solid–liquid separation .…”

Sodium oleate (NaOL), an anionic surfactant used in mineral processing, is challenging to quantify in aqueous solutions using UV spectroscopy. This study examined ultraviolet spectral shifts of sodium oleate with and without common pH regulators. Experimental results were supported by quantum chemical calculations at the CAM-B3LYP//6–31++G(d,p) level of theory. Two main absorbance peaks appeared in sequence, at 190 and 232 nm, corresponding to the π → π* and the n → π* electronic transitions of the CC double bond and COO– functional group, respectively. Under the typical concentration range used in adsorption and flotation studies, the first peak redshifted to reach λmax = 203 nm at 2 mM NaOL, while both solution deprotonation and protonation resulted in hypo/hyperchromicity. By influencing the electronic environment, acidic and alkaline treatments triggered a broadening and narrowing of the NaOL UV spectra. This difference in behavior was associated with the dissociative equilibrium of oleic acid, where protonation was favorable to molecular species, whereas deprotonation favored the ionic oleate species. The HOMO-LUMO excitation energies were higher in the protonated than in the deprotonated environment, explaining the broader spectra obtained experimentally in the former and higher reactivity in the latter. The peak disruptions give rise to significant discrepancies during quantitative measurements of NaOL in aqueous solutions, which may be managed by appropriate precautions and corrective techniques. These findings can be extended to systems similar to the oleate system and may guide experimental and data-processing procedures in UV spectrometry.
