In South Africa, dense medium separation accounted for 85% of the coal preparation, due to the very high levels of near-gravity material present in coal mined in this region. In China and Germany, jig washing is the dominant separation process used, again, due to the nature of the coal mined.

This grade of magnetite is required for washing coal re- duced to 100 mesh and is the grade expected to be used at Homer City. Only one brand of magnetite was used on the advice of Bureau of Mines personnel. The magnetite is mined, crushed, and ball mill ground until the 325 mesh re- quirement is met. It is dried by the supplier.

Industrially, the most common dense media is a suspension of fine magnetite and/or ferrosilicon particles. An aqueous solution as a dense medium is used in coal processing in the form of a belknap wash and suspensions in air are used in waterdeficient areas, like areas of China, where sand is used to separate coal from the gangue minerals.

The coal beneficiation or coal preparation process separates inorganic impurities from raw mined coal, reducing the concentration of unwanted material or gangue and thereby providing improved combustion characteristics to the fuel produced. The commonly used beneficiation methods for coal sorting and processing include jig separation, heavy ...

Magnetite is expensive, however, and an any improvement in recovery will likely pay for itself quickly over time. "The existing systems perform well as long as they are operated properly," said Jose Marin, director, minerals and materials processing for Eriez. "However, we believe these hybrid systems could achieve nearly recovery.".

Introduction. A coal dense medium separation (DMS) plant makes use of the principle of density separation to upgrade mined coal and produce metallurgical coal or power station coal. The objective of the DMS plant operation is to produce coal product within a minimum quality specification and maximum possible yield (England et al., 2002).
