A coal preparation process includes a dense medium coal separator which utilizes a magnetite media for separating raw coal from refuse. A sieve receives coal from the separator and is utilized to drain a portion of the magnetite media from the coal before the coal is passed into a new magnetite reclaimer wherein paddles agitate the coal causing abrasive contact between
Sep 22, 2003 Magnetite is the medium solids commonly employed for coal preparation. Most magnetite are produced as a by-product of iron ore processing. Demand for magnetite is expected to increase continuously. The increasing cost of magnetite has led to a growing interest in recovering magnetite from alternate sources such as power station fly ash.
In this study, enrichment methods for coal fly ash (CFA) from Omsk thermal power station No. 4 (TPS-4) were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared
magnetite can be used in a coal dense medium process by applying a magnetic field around a DMS cyclone, which consequently stabilises the coarse medium. EXPERIMENTAL PROCEDURE The test work process focused on the application of a weak magnetic field around a dense medium cyclone. The tests were done using medium only. Magnetite Samples

May 22, 2016 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.

today but the history shows that the application of cyclones in fine coal processing has not been nearly as successful as in the processing of coarser coal. There is a perception in the coal processing industry that dense-medium cyclone processing of fine coal is expensive, that it consumes much magnetite and that the

Magnetite is produced as a by-product of the phosphate mining process of Foskor. At our processing plant in Phalaborwa Idwala Magnetite upgrades this material by magnetic separation and fine milling for supply to the coal industry as a heavy separation medium (for coal washing).
Sep 30, 2007 The coal cleaning experiments were carried out on various size fractions of Pennsylvanias bituminous coal, Rushton coal. Angular magnetite was used as the host material to enhance segregation. The performance of the coal cleaning process was measured with the aid of sulfur and ash removal efficiencies.
The heavier specific gravity of magnetite aggregates allow a more aggressive backwash in the cleaning phase without loss of product, and because magnetite is magnetic it can be easily scavenged back from waste water streams for reuse. Magnetite is an essential part of the heavy media process in coal mining.
