“…In recent years, a substantial amount of research has been focused on the possibility of obtaining critical elements from coal, coal ashes and coal mining waste (Huang et al, 2000;Dai et al, 2005;Seredin and Finkelman, 2008;Dai et al, 2014aDai et al, , b, 2020Sun et al, 2015;Ward, 2016;Finkelman et al, 2019, Zhao et al, 2019aAdamczyk et al, 2020;Wang et al, 2020;Shen et al, 2021). Coal and coal ashes are regarded as new sources of critical materials, especially for rare earth elements (e.g., Seredin and Dai, 2012;Finkelman et al, 2018;Zhao et al, 2018Zhao et al, , 2019.…”

The distribution of selected critical elements in the sedimentary rocks of the Carboniferous coal‐bearing series within the Polish Coal Basins is presented. Critical elements such as Be, Mg, Si, P, Sc, V, Co, Y, Nb, In, Sb, La, Ce, Hf, Ta, W, Bi were analysed using inductively‐coupled plasma mass spectrometry (ICP/MS). Concentrations of elements such as Sb, Bi, In and, to a slightly lesser extent, Nb, as well as Sc, show average concentrations higher than those from the upper continental crust. The average concentrations of elements like Hf, Mg, P, Y, La, and Ce are slightly lower than in the upper continental crust. Other elements, such as Be, Co, Si, Ta, W and V have average concentrations that are similar, but slightly enriched or slightly depleted, relative to the upper continental crust. The research showed enrichment of some critical elements in the analysed samples, but not high enough that extraction would be economically viable. Statistical methods, which include correlation coefficients between elements and cluster analysis, reveal a strong positive correlation between elements like Be, Bi, Nb, Sc, Ta, W and V. Very high, almost total, positive correlation is also noted between La and Ce.

“…With the increasing attention to ensure robust raw material supply chains, more European deposits have been studied for their CRM supply potential, from Finland [ 77 ] to Greece [ 78 , 79 ], in central Europe [ 80 , 81 ], and from Poland [ 82 ] to Portugal [ 83 , 84 ]. With the right technology, the political and social agreement deposits can become mining sites, if economically feasible.…”

This editorial reports on a thorough analysis of the abundance and scarcity distribution of chemical elements and the minerals they form in the Earth, Sun, and Universe in connection with their number of neutrons and binding energy per nucleon. On one hand, understanding the elements’ formation and their specific properties related to their electronic and nucleonic structure may lead to understanding whether future solutions to replace certain elements or materials for specific technical applications are realistic. On the other hand, finding solutions to the critical availability of some of these elements is an urgent need. Even the analysis of the availability of scarce minerals from European Union sources leads to the suggestion that a wide-ranging approach is essential. These two fundamental assumptions represent also the logical approach that led the European Commission to ask for a multi-disciplinary effort from the scientific community to tackle the challenge of Critical Raw Materials. This editorial is also the story of one of the first fulcrum around which a wide network of material scientists gathered thanks to the support of the funding organization for research and innovation networks, COST (European Cooperation in Science and Technology).

“…Moreover, it is crucial to establish what types of emitted compounds contain REEs, and to analyze the characteristics of these compounds. It was presented in the most recent studies [7] that the concentration of REEs in fly ashes emitted from the Polish energy sector can reach over 300 ppm. The results of some studies [8] suggest that soil fertilizers can contain some amount of REEs, and extensive use of fertilizers can be a cause of increased concentration of REEs in arable soils.…”

“…As was analyzed by Adamczyk et al [7], fly ashes emitted by industrial and energy sectors contain significant amounts of REEs that occur in the form of TMPs, and therefore they can be detected using measurements of κ. Moreover, as it was previously studied by Cao et al [4], REEs contained in industrial fly ashes are accumulated mostly in organic and humic soil horizons, like other pollutants.…”

The purpose of this study was to use fast geophysical measurements of soil magnetic susceptibility (κ) as supplementary data for chemical measurements of selected light rare earth elements (REEs) in soil. In order to ensure diversity in soil conditions, anthropogenic conditions and types of land use, seven areas were selected, all located in regions subjected to past or present industrial pollution. Magnetometric parameters were measured using a selected magnetic sensor that was specially designed for measurements of soil cores and were used to classify collected soil cores into six distinctive types. The analysis of REEs concentrations in soil was carried out taking into account the grouping of collected soil samples based on the type of study area (open, forested and mountain), and additionally on the measured magnetometric parameters of collected soil cores. A use of magnetometric measurements provided different, but complementary to chemical measurements information, which allowed to obtain deeper insight on REEs concentrations in soils in studied areas.
