LOSS LEVEL OF MAGNETITE IRON AT WET SEPARATION

Abstract
The article presents the studies of tailing operation flowsheet of Abagur factory. The magnetic, chemical analysis of the overall tailings, as well as the measured magnetic characteristics of the products has been submitted. The iron content of magnetite in the tailings has been averaged in 2013 and made up ~0.9 %. The experiments have confirmed that the main losses are associated with magnetite thin classes, their low magnetic parameters. The loss of magnetite decreases with increasing separation of the field. The factory replaced 45 % of barium ferrite magnetic systems separators PBM 90/250 by composite neodymium-iron-boron systems; therefore, the field was increased from 111 to 175 kA/m. It is recommended to complete the modernization of magnetic separators systems of all factory operations and to set condensation separators for regeneration of suspensions with a field of 190 kA/m. As a result of the reconstruction magnetite iron loss level in the factory can be achieved nearly ~ 0.45 – 0.55 %.
