    01/10/2010  Brazilian concentrators employ cationic reverse flotation to concentrate iron ore fines below 105 μm. The commonly used reagents are Gypsum starch and ether amine, respectively, depressant and frother/collector (Araujo et al., 2005). The use of depressant blends is not a common practice in Brazilian iron ore concentrators.
