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 ...

2019-8-1  The effect of magnetite as a magnetic seed on the flotation separation of fine hematite and quartz was studied by reverse micro-flotation and sedimentation. The results demonstrate that fine magnetite could selectively report to the pulp product with hematite particles, forming aggregates that avoided attachment to quartz particle surfaces.

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 ...

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 easilier adsorbed on the quartz surface and improved ...
