Wet magnetic separator using our newly developed neodymium-iron-boron magnetic material having high magnetic permeability and magnetic energy of a magnetic source as a permanent magnetization, magnetic induction and analyzed according to the characteristics thereof and the actual sorting operation, scientific design, careful manufacture Made. The device may optionally minerals are: manganese ore, limonite, hematite, goethite, limonite, siderite, chromite, tantalite, niobium, titanium, iron, cerium, monazite, sulfur manganese , psilomelane, pyrolusite, rhodochrosite, wolframite, ilmenite rutile, Tieying rock, apatite, xenotime, olivine, germanium, sulfur and copper ore, ankerite, bastnasite , biotite , epidote, garnet, antimony, serpentine and non-metallic iron removal. After sorting by the wet magnetic separator, it can generally increase the grade by 10%-30%. The magnetic separation and tailing process of the magnetic separator is to crush the ore to 5 mm or less, and then perform wet magnetic separation and tailing with a permanent magnet medium field magnetic separator. This process is particularly important for energy saving, efficient use of extremely poor iron ore and improved final iron concentrate quality. In order to develop iron ore with a grade of less than 20%, the experimental study uses a high-pressure roller mill to finely break the ore to less than 3 mm, and the midfield strong wet magnetic separation removes about 40% of the coarse tailings, and raises the iron grade of the milled material to About 40%, after re-grinding and re-election, the final iron concentrate is obtained. The final iron concentrate grade is over 65%, the SiO2 content is below 4%, and the tailings grade is below 10%. Further, using a hammer mill beneficiation plant - the field strength of permanent wet magnetic separation process, the material selected for the particle size accounts for 80% or more -5mm, throwing coarse tailings may be about 30% yield in addition to 40%.
