This study is focused on fabrication and characterization of mixed matrix poly ether sulfone based nanofiltration membrane by phase inversion method. The effect of different amounts of Ilmenite (FeTiO3) particles as inorganic filler additive in the casting solution on physic-chemical characteristics of membranes was studied. Scanning electron microscopy, surface analysis, water content, contact...

To investigate the acquisition mechanism of high and stable natural remanent magnetization (NRM) in rocks of the Russell Belt, Adirondack Mountains, New York, we examined the exsolution microstructures and compositions of magnetic minerals using three samples with different magnetic properties. The samples contain titanohematite with ilmenite lamellae, end-member hematite without lamellae and r...

The experimental Ti K-edge X-ray absorption near edge structure (XANES) spectrum of the mineral ilmenite was recorded. The theoretical Ti K-XANES spectra of ilmenite were simulated using both the self-consistent real-space full-multiple scattering theory within the muffin-tin approximation for the potential shape and the full-potential finite difference method. The comparison of the theoretical...

We performed a series of experiments at high pressures and temperatures to determine the partitioning of a wide range of trace elements between ilmenite, armalcolite and anhydrous lunar silicate melt, to constrain geochemical models of the evolution of the interior of the Moon. Experiments yielding partition coefficients were performed in graphite-lined platinum capsules at pressures and temper...

Ilmenite disseminated grain size is relatively fine, and it must be finely ground to fully separate ilmenite from gangue then produce fine-grained minerals, which deteriorates flotation. A novel method using buoyant carriers improve the recovery of fine in froth flotation was introduced this study. Hydrophobized glass bubbles (HGB) as carrier materials were obtained by an efficient, simple modi...

This paper reports the preparation of sulphur polymer cements (SPCs) incorporating waste ilmenite mud for use in concrete construction works. The ilmenite mud raw material and the mud-containing SPCs (IMC-SPCs) were characterised physico-chemically and radiologically. The optimal IMC-SPC mixture had a sulphur/mud ratio (w/w) of 1.05 (mud dose 20 wt%); this cement showed the greatest compressive...

In this work, the effects of temperature, acid concentration, and mechanical activation on dissolution of ilmenite were studied using the statistical design of experiment technique. Mechanical activation was carried out using a planetary ball mill in dry mode, and the resulting structural changes were characterized by the particle size analysis, specific surface area measurements, and X-ray dif...

Ilmenite is a vital raw material for the production of metal titanium and titanium-containing materials. In this paper, microstructure chemical transformation natural ilmenite in air atmosphere were investigated by analysis XRF, X-ray diffractometer, SEM-EDS. Results showed that untreated had three layers after oxidation at 800 °C 60 min, which Fe2O3, TiO2 inside mixture layer Fe2O3 turn. Subse...

Oxygen carrier aided combustion is a process that utilizes oxygen carrying particles in fluidized bed to transport from oxygen-rich oxygen-poor regions the reactor. A commonly used oxygen-carrying material ilmenite (FeTiO3) which naturally occurring mineral. At higher partial pressures can react pseudobrookite (Fe2TiO5) and thereby take up oxygen. Upon reduction of oxygen-lean locations release...
