Magnetic separation of magnesite and dolomite was carried out by using induced roll magnetic separator. A magnesite concentrate of 1.12% CaO with 46.02% yield was obtained from a feed of 5.73% CaO. The ore mineralogy reveals that dolomite is associated with goethite, whereas, magnesite is associated with hematite and magnetite.

The heavy-media separation process, or HMS, employing ferrous media, usually ferrosilicon and/or magnetite, is the most generally used process for sink-float separations. A stable medium over the range of specific gravities from 1.25 to 3.40 can be maintained within close limits and is cleaned and recovered by magnetic means.

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 …
