    01/01/2013· The objective of coal preparation is to separate valuable coal from unwanted mineral matter. Separation is achieved by exploiting differences in the physical (e.g., density, size, shape) and physico-chemical (e.g., wettability) properties of coal and mineral matter. Ideally, the plant-wide separation should be as efficient as possible in order to maximize coal yield at a given quality

  • Coal preparation plant Wikipedia

    15/06/2006· A coal preparation plant is a facility that washes coal of soil and rock, crushes it into graded sized chunks, 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 content, the greater its market value and the lower its transportation costs.
