Vanadium titanomagnetite is an important mineral resource. It a raw material for ironmaking, vanadium extraction, strategic metal titanium production, and dioxide production. In this study, high chromium (High-Cr VTM) ordinary iron ore were used as materials pelletizing. The effect of V2O5 on the preparation properties High-Cr VTM pellets was studied. influence green pellets, compressive streng...

The sea sand vanadium titanomagnetite has the problems of coarse particles, difficult agglomeration, and poor sintering performance. It is for iron steel enterprises to use it as an ironmaking raw material in large quantities. In this work, different methods were adopted optimize high-temperature characteristics increase usage ore. Based on characterization analysis basic physical chemical prop...

In order to pursue the goal of low-carbon ironmaking, a new type humic acid (HA)-based binder was applied preparation oxidized pellets from vanadium-bearing titanomagnetite (VTM) in this work. Effects HA (or with limestone) on balling, preheating, and roasting behaviors VTM were comparatively studied bentonite. The embedded features each mineral phase sintered pellets, especially crystallizatio...

Through thermodynamic smelting experiments, nonisothermal and isothermal kinetics the effects of CO2–containing gas injection on chromia–bearing vanadiferous titanomagnetite ore were investigated. The experiments at 900 °C, 1000 1100 1200 1300 CO2 concentration 0, 10 vol.%, 20 30 vol.% studied. samples after analyzed through calculations characterized by XRD, XRF, XPS, SEM. results show that si...

Introduction: Most martian meteorites are highly shocked, with plagioclase transformed to maskelynite or even melted and partially crystallized [1,2]. These responses to shock conditions on Mars provide clues to the nature of the ejection events for martian meteorites and to local shock conditions. Where new-to-science phases are discovered, meteoritic occurrences can also inform the study of e...

Introduction: Melt breccias generated by a bolide collision in the vicinity of Bahía Blanca, Buenos Aries Province, Argentina at the Miocene-Pliocene Boundary (5.28 ± 0.04Ma) contain sand-sized meteoritic clasts [2], reviewed in [1]. The clasts exhibit textures and mineral assemblages (Fig. 1) most similar to quenched volcanic angrites, especially Asuka 881371 and Sahara 99555. They contain aci...

Zan lateritic horizon is located about 25 km southeast of Damavand, Tehran Province. This horizon developed as stratiform in lower part of shales and sandstones of Shemshak Formation (Jurassic). Mineralogical investigations show that diaspore, hematite, goethite, anatase, and kaolinite are the principal minerals of this horizon accompanied by lesser amounts of accessory minerals like boehmite, ...
