[PDF] 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 …
Physical separation of iron ore: magnetic separation
It is very difficult to produce a high quality iron ore concentrate by magnetic separation alone for this type of iron ore. The feed ore is first ground using ball mills down to about 90% −75 micron particle size. Several drum LIMS are then used to take out the magnetite particles, while a number of drum MIMS (0.4 T Middle Intensity Magnetic ...
