A coal preparation plant (CPP; known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash 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 content, the greater its market value and the lower its transportation costs.
