Due to their high magnetization, superparamagnetic iron oxide nanoparticles induce an
important decrease in the transverse relaxation of water protons and are, therefore, very …

Sulfur is a harmful impurity in iron ore, which seriously affects the subsequent smelting
process and product quality. In this study, a novel process of hydrogen-based mineral phase …

Abstract Fe 3 O 4 (magnetite) nanoparticles (NPs) were synthesized using a co-precipitation
method, and then annealed at various temperatures between 50 and 850° C for 1 h in air …

Pinyon and juniper are invasive woody species in the western United States that occupy
over 30 million hectares of land. The US Bureau of Land Management (BLM) has embarked …

The mechanism and kinetics of the reduction of hematite to magnetite in a laboratory-scale,
micro-fluidized bed reactor were isothermally investigated. The procedure consisted of the …

A recycling process of iron from red mud by magnetic separation is proposed, in which iron
oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with …

Efficient utilization and clean recycling of low-grade refractory iron ore are essential to deal
with the fast depletion of high-grade iron ore. A semi-industrial test of suspension …

Magnetic carbon activated (MAC) Fe 3 O 4-loaded activated carbon was developed using
termite feces and sulfuric acid as the carbon-modifying agent. The key point of the synthetic …

Phase transformation of weakly magnetic iron minerals into a strongly magnetic magnetite is
a promising technique for iron ore beneficiation with the further magnetic separation …

Hematite-containing material is accumulated during exploitation and beneficiation of
magnetite ore, thus forming tailings and other industrial wastes. Hence, processing the low …
