High gradient magnetic separator makes iron removal

2021-5-14  The main impurities of feldspar are limonite, hematite and mechanical iron produced by grinding. In order to effectively remove the weak magnetic limonite, hematite and other impurities in feldspar ore, we used a high gradient magnetic separator with background magnetic field strength of 13000gs to remove iron in feldspar production line.

High Gradient Magnetic Separation of Iron Oxides

Goethite, hematite, lepidocrocite, and anatase are concentrated in the magnetic fraction, while quartz is concentrated in the tailings. Chlorite is effectively concentrated in the magnetic fraction. Although mica, vermiculite, and smectite are often found in both the tailings and the magnetic fraction, vermiculite and mica appear to be more concentrated in the magnetic fraction.

PULSATING HIGH GRADIENT MAGNETIC SEPARATION

2016-12-27  Abstract: Pulsating high gradient magnetic separation (PHGMS) for removing trace amounts of iron impurities from a quartz ore was investigated using a lab-scale PHGMS separator, and its performance was further confirmed through a pilot-scale PHGMS separator. The results of this investigation indicated that PHGMS is effective for removing the iron impurities from the ore. By applying the lab-scale separator with a rod matrix of 1.5 mm diameter to the ore containing 0.063% Fe2O3, a concentrate assaying 0.0079% Fe2O3 with 89.82% iron removal rate was achieved through a two-step purification of PHGMS. It was found that the separation performance of this lab-scale separator was closely correlated with the wire diameter of matrix, pulsating frequency and background magnetic induction. Compared with the separation characteristics of PHGMS in beneficiating feebly magnetic metallic ores, it is clear that a much gentler pulsating intensity and a much higher background magnetic induction are both required to maintain a high iron
