Canadian coal preparation plants
, 1986 All Canadian coal destined for export abroad or to distant domestic markets must be beneficiated to remove mineral matter and to produce a high-quality, uniform, saleable, thermal or coking coal product. The geological setting in which coal is mined in Canada varies in the extreme; from steep, thick, often contorted seams in the mountains of western ...
