A coal preparation plant takes coal from a mine and cleans it for transport. When coal comes out of a mine, it is full of impurities. These impurities lower its overall value, reduce its usefulness and increase the cost to ship it. Since impure coal is so detrimental to its use, most coal mining companies own or use a coal preparation plant.
