The goal of roasting is to reduce the weakly magnetic iron ore to the highly magnetic magnetite and realize the separation of magnetite and gangue(Li et al., 2021; Qin et al., 2023; Rzepa et al., 2016; Yuan et al., 2020a). In addition, flotation for magnetic iron concentrate is used to deprive phosphorus and obtain low-phosphorus iron concentrate.

May 15, 2019 In this research, the efficiency of magnetic separation methods for processing of a low-grade iron pigments ore (red ochre) has been studied. Based on the mineralogical analyses (XRD), thin section and polish studies, the reserve is an iron sedimentary deposit with an average Fe grade of %31.3.
The suspended magnetic separator absorbs iron metal on the conveyor belt's surface, whereas the roller magnetic separator absorbs iron metal near the bottom of the belt. As a result, they are frequently connected in series to improve the efficiency of ferrous metal recovery in practical applications. ... The separation is between economic ore ...
Magnetic separation is widely used. All materials with magnetism in the magnetic field can be treated by magnetic separation, which is the main method to treat iron ore. All lean magnetite ores need to remove gangue minerals such as quartz through weakly magnetic field magnetic separators to improve the iron grade of concentrate.
