The reagents ...

Reverse flotation of ultrafine magnetic concentrate by ...

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

Iron Ore Reverse Flotation Introduction - Xinhai

In iron ore direct flotation process, a sort of direct flotation reagent is added and then works under specific conditions. The floating material is mainly iron concentrate. On the contrary, iron ore reverse flotation uses reverse flotation regents to work under given conditions, and its floating material is mainly gangue mineral.

Effect of reverse flotation on magnetic separation ...

Abstract. 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).

Reverse flotation separation of hematite from quartz ...

Aug 01, 2019· 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.
