iron ore gravity separation

iron ore gravity separation

Coarse hematite (Fe 2 O 3) is recovered by gravity separation while fine magnetite (Fe 3 O 4) is separated from gangue minerals by magnetic separators. Some iron ore processing plants [1] combine the two approaches to produce the iron oxide concentrate destined to the steel producers. This paper deals with the gravity concentration of iron ores.
