The dominant areas, where the drum magnetic separators are used, are the processing of magnetite, titano-magnetite, and vanadic titano-magnetite ores. Figure 3 shows the wet drum magnetic separator and its operation for vanadic titano-magnetite. The technical specifications of applied wet drum magnetic separators are illustrated in Table 2.
Magnetite processing involves wet grinding, as opposed to hematite's dry grinding, which produces finer particles and so improves the efficiency of the beneficiation process. The magnetic separation process used with magnetite is also more energy-efficient than gravity separation or flotation, which are employed in hematite processing, and ...
