Effect of reverse flotation on magnetic separation ...

Aug 09, 2012  Reverse flotation studies on magnetite samples have revealed that the use of starch as a depressant of Fe-oxides has a hydrophilic effect on the surface of Fe-bearing silicates and significantly decreases Fe in the silica-rich stream when used in combination with an amine (Lilaflot D817M). In this study, the effect of reverse flotation on the optimization of products obtained from magnetic ...

Jul 01, 2019  1. Introduction. Reverse cationic flotation is an effective process used in the beneficiation of oxidized iron ores (Filippov et al., 2010, Eisele and Kawatra, 2007, Nakhaei and Irannajad, 2018).In this process, quartz, which serves as the main gangue mineral, is floated with cationic collectors (amines) (Filippov et al., 2014, Araujo et al., 2005). ...

Inhibiting the amine flotation of magnetite through ...

Apr 01, 2018  Even low amine adsorption promotes flotation of magnetite, however, so that depressants are used to inhibit the flotation of the iron oxide. Starches are the universal depressants due to their high affinity towards the surface of iron oxides ( Araujo et al., 2005 , Filippov et al., 2014 , Shrimali and Miller, 2016 ).

Jan 01, 2010  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 not absorbed on the surface of quartz.

Reverse anionic flotation of magnetite is conducted at a higher pH value (pH 11–12) than reverse cationic flotation (pH 10–10.5). Since the point of zero charge (PZC) of pure magnetite is around pH 6.5, the surface charge of magnetite in reverse cationic flotation (pH 10–10.5) would be less negatively charged than that at pH 11-12 (Li et ...
