Recovery of Magnetite from Coal by Dry Beneficiation

The use of magnetite as a medium in the wet processing of coal has been used since the early days of dense medium separation. The high magnetic susceptibility and density of magnetite make it an ideal medium to use in wet coal beneficiation because it is relatively easily and successfully recoverable.

Coal Beneficiation - an overview | ScienceDirect Topics

Joan S. Esterle, in Applied Coal Petrology, 2008 3.7.2 Mineral and Trace Element Partitioning. As noted, one of the fundamental reasons for coal beneficiation is the reduction of ash yield and deleterious minerals and elements with an inorganic affinity. The partitioning of major, minor, and trace elements depends on the degree of liberation of the minerals, their inorganic versus

Finely ground magnetite, a dense form of iron oxide, is used in the preparation of the heavy medium suspensions used in the separation units. The average magnetite loss from a large heavy medium coal-cleaning facility can be as large as 10,000 to 13,000 tons per year, representing nearly one million dollars of annual operating costs.
