The content of valuable elements was determined by the technique of inductively coupled plasma mass spectrometry (ICP-MS) in the material collected from three regions of southern Poland. A mixture of waste (including fly ash, furnace slag) from heat and power plants using coal for thermal transformation processes was an object for testing. Part of the research project was to identify a share of the rare elements in the collected samples with a selected grain class of <0.045 mm.}, type={Article}, title={The Concentration of Rare Earth Elements in the Polish Power Plant Wastes}, URL={http://journals.pan.pl/Content/122697/PDF/Archiwum-67-1-02-Baron.pdf}, doi={10.24425/ams.2022.140700}, keywords={Coal burning wastes, rare earth elements (REE), granulometric classification}, }
