Most of the 14 workable coal seams in the State of Missouri are considered to be high in ash and sulfur contents and need beneficiation in order to meet customer and Environmental Protection Agency requirements. If proper beneficiation methods can be designed, more Missouri coal will be mined and used within the state.
The objectives of this research are (1) to draw the washability curves of important Missouri coal seams in order to determine their washability characteristics, and (2) to determine the flotation characteristics of the same seams.
Tests conducted on 20 samples taken from Bevier, Croweburg, Mulky, and Summit seams showed important differences in ash, sulfur, and pyrite contents. Their wash- ability and flotation characteristics were also quite variable.
