Mine mouth coal for power plants undergoes very little to no processing, while metallurgical or thermal coal for export usually undergoes washing to remove rock particles. Most coal mines that mine coal for power plants simply dig it up and send it to the power plant for burning. Very little processing. Some times a mine might blend low grade coal with higher grade coal to ensure a constant ...
