Coal Washing
Coal is a type of sedimentary rock that is formed by buried vegetation that is transformed by pressure and heat over long periods of time. Coal will eventually turn into diamond formations with enough time, pressure and heat. Impurities include slate and other non-organic rocks etc.. Washing coal increases its efficiency and quality, therefore ...

Coal mining
Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create …
Magnetite
Magnetite (Fe3O4), like hematite (Fe2O3), is a form of iron ore. It is a highly magnetic substance used primarily in steel manufacturing and coal washing. There are more than 20 identified magnetic deposits and prospects located across South Australia, Western Australia, Queensland and Tasmania. Magnetite occurs in nearly all igneous and ...
CHAPTER 3 Coal Preparation and Cleaning
of these boilers to coal requires coal with a very low ash content (1-2%) which is finely ground, mixed with oil or water, and stabilized with surface-active agents. A properly prepared coal slurry can be stored, pumped, piped, and handled like fuel oil. But to achieve the low ash content required, in most cases
Coal Preparation | SpringerLink
Coal preparation, which may also be called washing, cleaning or processing, is the methodology by which coal feedstocks are upgraded in order to reduce freight costs, improve utilization properties and minimize environmental impacts.

Magnetite Recovery in Coal Washing by High Gradient Magnetic …
Drum separators are affected by the amount of magnetics in the slurry. The recovery decreases in dilute slurries — an effect not seen in high gradient separators. Also they are limited to 20% solids or less in the feed and 60-70 gpm/ft of drum width if the non-magnetics content is re- quired to be less than 10%.
