Magnetic scavenging of ultrafine hematite from itabirites - SciELO

Magnetic separation has gained force with the advent of high gradient and field intensity continuous machines. A comparative pilot study was realized in order to magnetically recover hematite from a typical slime thickener underflow of a mill plant from Quadrilátero Ferrífero (Minas Gerais, Brazil). Two rotor (carrousel) high...

Hematite: A primary ore of iron and a pigment mineral - Geology.com

Hematite is not magnetic and should not respond to a common magnet. However, many specimens of hematite contain enough magnetite that they are attracted to a common magnet. This can lead to an incorrect assumption that the specimen is magnetite or the weakly magnetic pyrrhotite. The investigator must check other...

Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, or deep purple to rusty red. The iron itself is usually found in the form of magnetite (Fe 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite...
