“…As it was noted for chalcophile elements, the mode of binding of Th and U in coal is probably not a permanent identification feature of raw coal for the entire deposit or basin. It may be different in raw coal from the individual lithostratigraphic members of a given seam and may even differ in individual parts of a single coal bed [5,27,40,60,61]. In addition, the content and mode of binding elements in feed coal may be different before and after removal in the plant for the enrichment of mineral matter from coal.…”

“…The identification of groups of minerals that have the greatest influence on trace elementals content in coal makes it easier to forecast the efficiency of various chemical and mechanical procedures for purging ecotoxic elements (e.g., refs. [1][2][3]); it also has an influence on more conscious forecasts concerning the quantities of elements released into the environment following coal combustion [4][5][6][7][8]. Combustion of hard coal in thermo-electric power stations provides people with electricity and heat, but also raises concerns about the possibility of environmental pollution.…”

Based on the results of tests on feed coal from the Lublin Coal and Upper Silesian Coal Basin and its fly ash and slag carried out using X-ray diffraction and X-ray fluorescence analysis, atomic emission spectroscopy, and scanning electron microscopy, it was found that in feeds, coal Th is associated with phosphates and U with mineral matter. The highest Th content was found in anhedral grains of monazite and in Al-Si porous particles of fly ash of <0.05 mm size; whereas in the slag, Th is concentrated in the massive Al-Si grains and in ferrospheres. U is mainly concentrated in the Al-Si surface of porous grains, which form a part of fly ash of <0.05 mm size. In the slag, U is to be found in the Al-Si massive grains or in a dispersed form in non-magnetic and magnetic grains. Groups of mineral phase particles have been identified that have the greatest impact on the content of Th and U in whole fly ash and slag. The research results contained in this article may be important for predicting the efficiency of Th and U leaching from furnace waste storage sites and from falling dusts to soils and waters.

“…This was done for a representative of UK coals by Spears and Zheng (1999) and most recently for other coals and lignites by Chatziapostolou et al (2006), Kalkreuth et al (2006) and Song et al (2007). There is considerable current interest in trace elements in coals as these, and other recent papers demonstrate (for example Brownfield et al, 2005;Wagner and Hlatshwayo, 2005;Dai et al, 2006;Parzentny and Lewinska-Preis, 2006;Yang, 2006;Hower et al, 2007). These are important papers that focus more on a comprehensive range of trace elements and comparisons with other coals, including global averages, than is the case in the present work.…”

“…Taki skład chemiczny popiołu węgla znajduje uzasadnienie w jego składzie mineralnym. W węglu tym, autor wcześniej zidentyfikował największą zawartość minerałów węglanowych (18,15%), dużą zawartość pirytu (3,62%) i małą zawartość minerałów ilastych (0,36%) (Parzentny i Lewińska-Preis 2006). Ponadto zaobserwowano większą zawartość Fe 2 O 3 i CaO oraz mniejszą zawartość SiO 2 , Al 2 O 3 , Na 2 O, TiO 2 i P 2 O 5 w popiele badanego węgla z północnego, niż z południowo-zachodniego rejonu badań (tab.…”

A total of 56 coal seam samples (from active and closed coal mines) representing USCB Paralic Series, were tested. It was determined that the tested coal has low content of mineral matter (especially in Hruśov Beds) as well as of Ag, As, Ba, Cd, Co, Cr, Cu, Mo, Ni, Rb, Sb, Sn, Sr, V and Zn. Only Mn and Pb content in coal is higher than in coal from other deposits around the world. There are differences in the values of physical and chemical, petrographic and geochemical indices of coal quality, between the northern and the south-western part of the USCB and in the profile of the Paralic Series. Thanks to the revealed correlations between the indices of coal quality, significant differences in the role mineral and organic substance play in concentrating some of the trace elements in the tested coal, were determined. Moreover, it was observed that an increase in the rank of coal (expressed with an increase in the value of R0 or/and Qsdaf or/and Cdaf), accompanies a decrease in the content of oxides of main elements in coal ash as well as sulfur and other trace elements in coal. The dependence was observed both in lateral and stratigraphic differences in the rank of coal. Mutual dependences between the indices of the rank of coal (R0, Cdaf, Qsdaf, Vdaf) in the northern and south-western area of the research and in Poruba Beds and Jaklovec Beds, were confirmed. It was determined that an increase in the value of Roga Index (RI) is accompanied by an increase in P2O5 content in ash of coal from the south-western part of the research area. It is probably a result of concurrence of a regional positive anomaly in the rank of coal and high P2O5 content in coal seams in the south-western part of the USCB. The observed increase in the value of RI, accompanying a decrease in the content of sulfate minerals, Cr and Ni in coal and Na2O in coal ash; results from the role the carbonisation process plays in distributing main and trace elements in the mineral matter of coal.
