DRY MAGNETIC SEPARATION OF MAGNETITE ORES
The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the research is to study the …

Magnetic separation: Separation generally adopts permanent magnet drum-type magnetic separator. Most magnetite beneficiation plants often adopt coarse-grained dry magnetic separation tailings. If ultra-lean magnetite ore is below 20%, the ultra-fine crushing-wet magnetic separation tailing process can be used before entering the mill.

In ilmenite plants, the raw ore is classified into coarse (+20 μm) and fine (−20 μm) fractions. The coarse ore can be effectively preconcentrated using conventional magnetic separators [1, 12, 13], and currently, SLon magnetic separator is being applied well in plants [14].However studies on fine ore are still being conducted in the start-up stages.
