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.

Sep 01, 2006· Adhesion to coal and the losses in the magnetic separator are the two main routes through which magnetite gets lost in a coal washing plant. In general, magnetic separators seem to contribute 20–40% of this loss, though this proportion will fall where adhesion losses are abnormally high, for example, with porous ores.

In the VNIR, magnetite and maghemite display low reflectance, around 2% for the former and 11% for the latter (Figure 6.6).In the 6000–14,000 nm wavelength region, magnetite reflects poorly, but its reflectance baseline shows an increase toward longer wavelengths with such a low degree that magnetite can only be indirectly indicated by a significant vertical offset in the spectrum (Schodlok

In the coal preparation plant, the run of mine coal undergoes a series of operations, including washing, wet screening, sedimen-tation and dewatering. The process requires the circulation of large volumes of water from which large volumes of waste water containing a variety of solid particles are generated.
