However, the magnetic separation of pyrrhotite from magnetite is problematic, due to their similar magnetic property and magnetic flocculation between pyrrhotite and magnetite [3]. Flotation has been commercially used as a method for removing pyrrhotite
The present invention relates to magnetic strength magnetic reverse floatation process in a kind of lean hematite thickness grading, gravity treatment, use two sections of Continuous Grindings,...
Flotation has been commercially used as a method for removing pyrrhotite from magnetite for high sulfurous iron ores [ 4 ]. In this process, pyrrhotite as a primary impurity is separated from iron ore using typically potassium butyl xanthate as the primary collector.
Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.
The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared to dry magnetic separation.
Magnetite can be produced as a by-product of copper operations, and as such is recovered from the concentrator floatation tails stream by magnetic separation. Typically 15% by weight of magnetite is removed through coal washing and re-cleaning the magnetic concentrate from the
problem in iron ore smelting process. However, the magnetic separation of pyrrhotite from magnetite is problematic, due to their similar magnetic property and magnetic flocculation between pyrrhotite and magnetite [3]. Flotation has been commercially used as a method for removing pyrrhotite from magnetite
The separation effect between pyrrhotite and magnetite was dramatically enhanced in terms of both magnetite recovery and desulfurization ratio. The ideal composition of the mixed collector was determined by batch flotation tests to be 40 wt % (BX) 2 and 60 wt % NaBX for pyrrhotite flotation.
Oct 27, 2020· Magnetic separation and froth flotation are common beneficiation equipment in the ore dressing process, mainly used to beneficiate the required ore. What is the difference in working methods between magnetic separation and froth flotation?
In this study, enrichment methods for coal fly ash (CFA) from Omsk thermal power station No. 4 (TPS-4) were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared to dry magnetic separation.
Weak magnetic separation verse flotation and weak magnetic concentration. According to the problems that some ore which is hardly to increase concentrate grade, that the SiO2 impurity is too much in iron concentrates, there are weak magnetic separation verse flotation and weak magnetic separation
Magnetite can be produced as a by-product of copper operations, and as such is recovered from the concentrator floatation tails stream by magnetic separation. Typically 15% by weight of magnetite is removed through coal washing and re-cleaning the magnetic
