ABSTRACT. In order to efficiently purify and recover the magnetite powder (dense medium) in the process of dry coal preparation of air-dense medium fluidized beds, a new type of fluidized dry magnetic separator was developed in this paper by changing the feeding device and mode, the location and structure of the separating tank, and the …

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 ...

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 …
