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. Canadian processors recover coarse hematite using spiral concentrators. Spiral concentrators have been used in the industry for more than 70 years [2].
