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
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.

2019 7 1 An improved performance was achieved using a pulse magnetic field during the reverse flotation of magnetite ore in a flotation column. The pulse magnetic field increased the recovery and grade of concentrate Fe by 1.12% and 4.22%, respectively, compared to the corresponding values obtained using no magnetic field.
Magnetite ores are among the most important sources of iron, which is in high demand in the global economy. Metallurgical properties of the magnetite concentrate significantly depend on
Compared with the SLon magnetic separator, the operating cost of reverse flotation is much higher. The flow sheet in Figure 9.16 provides an example of how to minimize the feed to flotation to reduce the total production cost. The iron ore is composed dominantly of specularite with only about 0.5% magnetite, and the gangue mineral is mainly quartz.

2012 8 9 Reverse flotation tests were conducted on the agitated magnetic concentrate feed, and the result shows a significant upgrade of Fe compared to that obtained from the non agitated feed. Iron concentrations greater than 69%, and SiO 2 concentrations less than 2% with overall magnetite recoveries greater than 67% and 71% were obtained for zones 1
Magnetite ores are among the most important sources of iron, which is in high demand in the global economy. Metallurgical properties of the magnetite concentrate significantly depend on impurities of silicon and aluminum bearing minerals. These impurities have to be separated from ore by magnetic separation and flotation techniques. Reverse column flotation is one of the
2022 5 5 Reverse column flotation is one of the methods applied for reducing the content of impurities in magnetite concentrate. This method allows recovering impurities from ore in the froth product
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
