Recently, coal fly ash (CFA) has been considered as a source of these elements. The purpose of this study was to evaluate the REEs content in a CFA from a Brazilian coal power plant by instrumental neutron analysis, to classify it according to commercial purposes and to assess the weathering impact in the REEs content, since it is held in fields nearby the power plant. The results pointed no significant REEs leachability and indicated this CFA as a promising REEs source.openAccesscoalfly ashrare earthsneutron activation analysisraw materialschemical analysispower plantscommercializationArtigo de periódico10.1007/s10967-016-5026-836.52
