Starch is the universal depressant of iron oxides in iron ore flotation (Araujo et al., 2005, Ma, 2008), which also serves as a flocculant of ultrafine particles (Iwasaki et al., 1980, Iwasaki, 1989, Iwasaki, 1990). Without desliming prior to flotation, the consumption of starch was found to increase significantly.
