For Brazilian iron ore producers, reverse cationic flotation is preferred to obtain high quality concentrates from silicate ores. The SiO2 (silica) particles are rendered hydrophobic by amine (cationic collector) in alkaline conditions, while iron is depressed by the addition of starch. The injected air forms bubbles to which the silica

True flotation versus entrainment in reverse cationic flotation for the concentration of iron ore at industrial scale. The loss of iron-bearing minerals to the tailings, especially in the finest fractions (−44 μm), is a problem that must be endured due to the depletion of deposits containing high-Fe hematite.

Flotation experiments under pH 10.5 were performed using quartz/hematite artificial mixtures. The influence of particle size and monoamine unit consumption on the kinetic parameter was analyzed, in a fundamental level. The coarse quartz class was between 212 m and 600 m and the fine class was between 74 m and 212 m.
