This chapter introduces the principle of how low-grade iron ores are upgraded to high quality iron ore concentrates by magnetic separation. Magnetite is the most magnetic of all the naturally occurring minerals on earth and can be readily extracted by low-intensity magnetic separators from magnetite ores.
The recovery and concentration of ultra-fine iron ore can provide significant economic benefits. Presently, there are limited options available given the low settling rates achieved by conventional gravity separation and the relatively poor performance of reverse flotation.
