magnetite in coal processing

Craigmont Industries Process in Producing Magnetite

Magnetite's role in the preparation of Coal. The mining of coal, whether by underground or open pit methods, usually contains a degree of incombustible materials e.g rocks mud etc. Customers require their product, in particular metallurgical coal, to be of the highest calorific value so these non-burning impurities (ash) need...

Coal preparation plant - Wikipedia

A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships. The more of this waste material that can be removed from coal, the lower its total ash...
