This paper describes the way diverse iron ore types behave during desliming and flotation stages. According to Clemer, desliming prior to the reverse cationic flotation of iron ores started with the USBM process. Araujo et al. stated that efficient desliming requires an adequate dispersion degree of the particles in the pulp.
Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing, which reduces the loss of fine iron minerals entrained into the froth phase (Dobby, 2002). The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.

In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
a method for separating silicates from the titanium values in a titaniferous iron ore which comprises grinding the ore to -60 mesh size, pulping the ground ore in aqueous media, acidifying the pulp to a ph between about 3.0 and 6.0 by adding thereto an acid solution containing an ionizable fluoride ion, adding starch to said acidified pulp to depress the titanium values, adding to said pulp a cationic amine .

Iron ore must go through a lengthy pre-processing stage before it can be pelletized – a series of steps that work to beneficiate and concentrate low-grade ores. This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore.
Dec 16, 2010· The rejection of silica particles can be obtained by magnetic and flotation separation techniques. Overall, the BHQ ore can be enriched to 65.3wt% Fe at 61.9% iron recovery. A flowsheet has been suggested for the commercial exploitation of the BHQ ore.
