However, the iron metal loss in the de-sliming stage, which is an essential step in reverse cationic flotation, and the high reagent cost of amine collector are the common problems of reverse cationic flotation. Reverse anionic flotation rejects quartz by first activating it with the use of lime, and then floating it using fatty acids asInhibiting the amine flotation of magnetite through,Iron ore flotation began in 1931 and followed two routes: (1) flotation of iron oxides with anionic collectors and (2) reverse flotation of quartz and silica-bearing minerals using cationic collectors. Of these two routes, reverse flotation with cationic collectors (amines) remains the most popular approach used by the iron ore industry.
Research on hematite and magnetite flotation in the presence of starch indicates an almost full depression of Fe-oxides and, therefore, impossibility of their flotation by amines (Peres and Correa, 1996, Raju et al., 1997). As confirmed by numerous studies, starch is Amine Flotation of Feldspar from Magnetite Concentrate,The amine flotation of feldspar from magnetite concentrate was investigated using zeta potential measurements, Hallimond tube flotation tests and laboratory-scale flotation tests. The zeta potential of various feldspars (microcline, albite, anorthite, oligoclase and anorthoclase) were determined as a function of pH; the point of zero charge ranged from pH 1.4 to 2.5.
