Bicrystalline Hematite Nanowires
The Journal of Physical Chemistry B, 2005Bicrystalline nanowires of hematite (alpha-Fe(2)O(3)) have been successfully synthesized by the oxidation of pure iron. The product was characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy (TEM), high-resolution TEM in combination with focal series reconstruction, energy-dispersive X-ray spectroscopy, and ...

Ultrathin Polycrystalline Hematite and Goethite−Hematite Core−Shell Nanorods
Langmuir, 2009We have developed a facile synthesis route to 1D structures of ultrathin polycrystalline hematite and goethite-hematite core-shells. One-dimensional structures of pure hematite and the goethite-hematite core-shell with very small diameters were synthesized in aqueous solution at low temperature with a simple, rapid method based on the oxidation of ...

Ultrafiltration of Hematite Sol
Separation Science and Technology, 1996Abstract Ultrafiltration of a laboratory-made hematite sol was studied in a batch cell with an Amicon PM 10 membrane at 298 K. The effects of hematite bulk concentrations (2 to 10 kg·m−3), stirring conditions (0 and 400 rpm), and pressure (50 to 350 kPa) were investigated.

Plasmonic Gold−Superparamagnetic Hematite Heterostructures
Langmuir, 2011Bifunctional heterostructures composed of gold nanorods and hematite nanoparticle aggregates are prepared facilely through the hydrothermal decomposition of ferric acetylacetonate on the surface of the nanorods. The gold nanorod in the heterostructure is partially coated with the hematite nanoparticle aggregates. The hematite coating is porous.

Production of hematite concentrate from hematite-magnetite ore
Mining informational and analytical bulletin, 2020The main useful minerals in composition of hematite-magnetite ore are magnetite and hematite. Magnetite is extracted by wet magnetic separation in weak magnetic field with production of magnetite concentrate and nonmagnetic product. The nonmagnetic product is a feed of the processing circuit for hematite.
