Coal preparation plant - Wikipedia

A coal preparation 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.

aqueous solution is separated from the coal and the coal is washed to remove residual ferric salt. The elemental sulfur which is dispersed in the coal matrix is then removed by vacuum distillation or extraction with a solvent such as toluene or kerosene. The resulting coal is basically pyrite free and may be used as low sulfur.
