Typically, subbituminous coal is burned without needing upgrading, whereas metallurgical and thermal coals are sent in raw form to a preparation plant. To get a higher energy content and economic value for clean coal, a preparation plant washes raw coal, filters out impurities, such as rocks and other sediment, and crushes the ore to specified sizes for easier handling.
