Concentration of rare earth elements in the Polish power plant wastes

coal burning wastes,rare earth elements (REE),granulometric classification

The article presents the results of laboratory tests determining the concentration of rare earth elements (REE) in coal burning wastes to assess their economic usefulness. Valuable elements content of which was determined by the technique of inductively coupled plasma mass spectrometry (ICP-MS) in the material collected from three regions of southern Poland. Mixture of wastes (including fly ash, furnace slag), from power plants and heat and power plants using coal for thermal transformation processes was an object for testing. As part of the research project, share of rare earth elements in the collected samples and in the selected grain class <0.045 mm was determined.
