The flotation has been successfully applied to process the iron ore for the particle size (Ps) from 10 m up to 150 m. The presence of the slimes (Ps 10 m) is harmful on the reverse flotation of quartz, so they are usually prior removed by hydrocyclones. The main effects of the presence of slimes on the flotation are related to the increase on reagents consumption, the froth stability ...
