Effect of reverse flotation on magnetic separation ...

2012-8-9  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 ...

2019-7-1  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 ...

2018-4-1  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 ,

New applications of deep eutectic solvents for separation ...

2021-1-1  A aliquat 336/lactic acid deep eutectic solvent was used for the reverse flotation of magnetite for the first time. The deep eutectic solvent increased the total iron content of the feed ore from 53.02% to 66.80%, which was better than dodecylamine. The FTIR, zeta potential, contact angle, and XPS showed that the deep eutectic solvent was ...

Reverse Combined Microflotation of Fine Magnetite from

Magnetite is an essential iron-bearing mineral. The primary method of magnetite ore beneficiation involves successive steps of crushing, grinding, and magnetic separation. Reverse cationic flotation is used at the final stage to remove silicate and aluminosilicate impurities from the magnetite concentrate and reduce silica content to 1–3%, depending on metallurgical processing route ...
