2015-10-22  The cationic collector in the magnetite reverse flotation process is Lilaflot collector. When the dosage of the Lilaflot collector increase to 30-50g/t, the iron grade of the iron concentrate is up to 69.90%, the silica 2.80%, which is suitable for a direct reduction of iron concentrate. The sulfur content of the concentrate is an important ...

Reverse flotation separation of hematite from quartz ...

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.

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 ...

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 ...

2017-3-19  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 ...
