MODES OF OCCURRENCE OF ENVIRONMENTALLY· SENSITIVE TRACE ELEMENTS IN COAL

Coal utilisation, especially coal combustion, causes the release of many inorganic elements into the environment. Various pollution control procedures and devices are used by the coal industry to minimise the release of these elements. Selective mining and coal cleaning procedures reduce the amount of the inorganic constituents in coal prior to combustion. Electrostatic precipitators, chemical additives, baghouses, and flue-gas scrubbers reduce particulate and element emissions after combustion.
