Separation of magnetite concentrate before the last grinding stage

Abstract

For magnetite and titanium magnetite ores, it is possible to use technology with the separation of concentrate before the last grinding stage. The possibility of staged separation of iron concentrate is due to different physical-mechanical properties of magnetite and rock minerals. The results of industrial and laboratory tests on the use of special magnetic separators with special structure, Derrick screen and screw separators in iron ore dressing schemes are presented. A comparison of proven dressing methods is performed. The choice of a specific dressing method for the staged separation of magnetite concentrate before the last grinding stage is determined by the properties of the base ore and the economic justification.
