Continuous production of nanosized magnetite through low ...
This result led us to propose a conceptual model of nucleationandgrowth process of magnetite during low grade burial from ˜2 to ˜4 km depth. Ultrafine magnetite (≤20 nm) was predominant over single domain magnetite (>20 nm) for <4 km depth.

Hexagonal Plateletlike Magnetite as a Biosignature of ...
Though the soluble Fe(II) in the cultures can be high enough (Li et al., 2011b) to inhibit further mineralization of magnetite by the recrystallization mechanism (Roden, 2006), the ultrafine goethite on the surface of magnetite observed in this study may serve as the Fe(III) source for the continuous mineralization of magnetite.

Ecoefficient and costeffective process design ... Metso
Feb 24, 2015· A significant fraction of iron ore used in steel production comes from magnetite deposits. Magnetite iron ore requires significant beneficiation, which typically involves grinding to a particle size where magnetite is liberated from its silicate matrix. And grinding consumes a lot of energy. This article investigates ecoefficient alternatives for the process design for magnetite iron ore.

Iron(III) oxide Wikipedia
Partial reduction with hydrogen at about 400 °C produces magnetite, a black magnetic material that contains both Fe(III) and Fe(II): 3 Fe 2 O 3 + H 2 → 2 Fe 3 O 4 + H 2 O. Iron(III) oxide is insoluble in water but dissolves readily in strong acid, hydrochloric and sulfuric acids.

Aug 04, 2006· Magnetite particles with an average size of 39 nm and good monodispersity have been synthesized by coprecipitation at 70 °C from ferrous Fe2+ and ferric Fe3+ ions by a (N(CH3)4OH) solution, followed by hydrothermal treatment at 250 °C. The magnetite nanoparticles before the hydrothermal step display an average size of 12 nm and are highly oxidized when they are in contact .
