Coal preparation plant - Wikipedia, the free encyclopedia
A coal preparation plant (CPP) 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.
