The processes of iron ore flotation being either by means of mechanical cells or columns, are fed by particles whose sizes vary 10 and 150 m, the ultrafine particles (slimes) are removed by means of cyclone, for they affect the process in a negative way, and the top size is limited to values between 5% and 10% above 150 m.

In this paper, several studies describing the processing of iron ores via direct and reverse cationic and anionic flotation are reviewed. The objective of this review was to present and identify the effects of different flotation conditions on removal of specific impurities in iron ore such as quartz, alumina, phosphorous, and sulfur.

The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm . In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- droxides.
