This article aimed to separate ilmenite (FeTiO3) mineral from tin tailing applying a single splitter IRMS (Induced Roll Magnetic Separator). Ilmenite is the substantial main source for TiO2. work used air table middling feeding. The components of feeding using grain counting analysis were found as follows: cassiterite (48.61%), (21.36%), monazite (18.56%), pyrite (4.60%), zircon (5.85%), quartz...

New analytical and experimental data constrain the storage and equilibration conditions of the magmas erupted in 1912 from Novarupta in the 20th century’s largest volcanic event. Phase relations at H2O+CO2 fluid saturation were determined for an andesite (58.7 wt% SiO2) and a dacite (67.7 wt%) from the compositional extremes of intermediate magmas erupted. The phase assemblages, matrix melt com...

High-pressure ilmenite MnVO 3 shows a semiconductor to metal transition on heating that resembles of VO 2 . Clues correlation and band effects are observed suggesting borderline case between Mott Peierls scenarios.

The Bikilal layered gabbro-complex is composed of zones/layers of olivine/ pyroxene gabbro and hornblende gabbro. Within the hornblende gabbro, repeated lens-like thin and elongated bodies of hornblendite are found intimately associated with massive and disseminated ilmenite-magnetite bodies, in places with apatite. Petrological examination of the hornblende gabbro shows 50-55% hornblende, 40-4...

High-pressure (0.8 gigapascals) granulite facies garnet from Gore Mountain, New York, hosts multiple solid inclusions containing the low-pressure silica polymorph cristobalite along with albite and minor ilmenite. Identification of cristobalite is based on Raman spectra, electron microprobe analysis, and microthermometric measurements on the alpha/beta phase transformation. The cristobalite plu...

The mineral chemistry of diamond indicator minerals is used to trace mineralizations in primary rocks such as lamproites/kimberlites and secondary deposits. Subcalcic garnets magnesian ilmenites are both associated with the potential described many deposits Alto Paranaíba Igneous Province where several kimberlitic pipes alluvial occur. Our study was conducted on Romaria deposit (Brazil), garnet...

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...

[1] We constrain SH wave velocity structures near the 660-km discontinuity beneath South America and northeast Asia, using triplicated phases near the discontinuity recorded in the epicentral distance range of 10 –35 for three deep events. We then explore mineralogical and compositional models appropriate for explaining the inferred seismic structures between the two regions. SH velocity struct...

Heavy minerals have become an essential commodity in modern-day technology. The objective of this study is to examine the current status heavy mineral industry Sri Lanka. present also examines economic viability potential placer deposits, based on geochemical data. Field investigations suggested occurrence as beach-placers, and inland/raised beach deposits along coastline Geochemical results sh...

Abstract This work reported the successful synthesis of ilmenite-spinel (1 − x )NiTiO 3 - MnFe 2 O 4 ( = 0, 0.05 and 0.10) composites by a simple sol-gel method. Phase formation was analyzed X-ray diffraction All synthesized samples formed diphasic ilmenite-ferrite without any trace impurity or intermediate phase. The optical properties were characterized diffuse reflectance UV–visible spectros...
