Popis:	Relevant published information is reviewed and assessed for the effects of mining and beneficiation on trace elements in coal. In general, the concentrations of those elements associated with mineral matter are decreased to varying degrees depending on coal properties and beneficiation processes. The removal of much of the pyrite in coal means that consideration must be given to pyrite-enriched wastes. The removal of most trace elements by beneficiation is an environmental bonus. Proper control of wastes during mining and beneficiation should overcome potential problems from the mobilisation of trace elements.
