Abstract

Contains the results of research to reduce the loss of magnetite iron in the wet processing of iron concentrates in high magnetic fields. Magnetite iron losses due to the low value of the magnetic characteristics of thin – less 50 micron grade magnetite. To increase the magnetic force of attraction is necessary to raise the intensity of the magnetic field and its gradient separation. Wet magnetic analysis showed that the loss of iron in magnetite fields H = 480 kA/m half as much as in the field H = 80 kA/m; loss in the conditions of high-gradient separation to about 0.1 %. Loss of magnetite iron tailings Abagurskom concentrator averaged made in 2013 – 0.9 % in 2014 – 0.89 %. The factory upgraded separator 28 PBM90/250 to the replacement of magnetic systems ferrite barium neodymium-iron-boron; wherein the field strength is increased from 111 to 175 kA/m
