“…The average concentrations of Hf are 1.2 ppm and 8.3 ppm in coal and coal ash, respectively [38]. Nevertheless, the natural abundance of Hfis 11.6 ppm and 9.54 ppm in Chinese coal [27] and Indian coal [44], respectively. Meanwhile, the high concentration of Hf (Table S5) is explored in Chinese coal mines including Adaohai [45], Datanhao [46], Huayingshan [47], Xinde [42], Fushui [48] and Hailiushu [49].…”

Strategically critical elements are becoming significant for the rising demand of emerging energy-efficient technologies and high-tech applications. These critical elements are mostly geologically dispersed, and mainly recovered from recycled materials. Coal with high concentrations of critical elements is supposed to stable alternative sources. The abundances of critical elements in coal varies widely among different deposits and regions. The high concentrations of critical elements are found in many Chinese and Russian coal ores. The global mining potential ratio (MPR) is applied and suggests scandium, hafnium, cesium, yttrium, germanium, gallium, thallium, strontium and rare-earth elements could be potential recovery from coal. A number of benefits are expected with the extraction of critical elements during coal utilization.

“…Coal has a signi cant share of the fuel used in global power production in a wide geographical range due to feasible economic cost and its reliable reserve (Verma et al, 2015;. Major part of the worlds' electricity (nearly 37%) is generated from this fossil fuel (Bhangare et al, 2011;Saha et al, 2016;IEA Report, 2021). The presence of some potential hazardous elements (PHEs), e.g., Hg, As, Pb, Cu, and Zn, may contaminate or pollute the environment and damage the ecosystem (Finkelman, 2004;Dai et al, 2012).Combustion of coal in thermal power plants produces large amount of coal combustion residues (CCR) which are complex in nature (Vejahati et al, 2010).…”

“…Mineralogical analysis by XRD reveals that quartz, kaolinite, illite, dolomite, apatite, calcite, siderite, pyrite, rutile minerals are present in the studied coal samples. This focuses that coal are enriched with various minerals and have notable in uence of silicate, clay, sulphide, carbonate, phosphate, and oxide minerals(Ward, 2002;Saha et al, 2016). Minerals are the host of major and trace elements in coals which re ect the chemical quality of fuel utilised in thermal power plants(Dai et al, 2013).…”

Energy generation from coal poses an environmental drawback due to the abundance of some potential hazardous elements (PHEs). A few PHEs (As, Sb, Cu, Mn and Zn) are noticed in the coal collected from thermal power plants of India. Among them, As and Sb are depleted while Cu, Mn, and Zn are enriched in y and bottom ash. The short-and long-term exposure of these PHEs into the ecosystem by emission, deposition, and leaching causes environmental contamination as well as pollution and health hazards. The water-leaching experiment shows that these elements have feeble mobilisation tendency and low risk. The bioavailability test re ects that bio-uptake of these PHEs into the human system may be the origin of several diseases. Proper storage and recycling of the large amount of y and bottom ash is a serious concern of thermal power plants. Chemical characterisation of ash, including elemental mapping by scanning electron microscope, calculated enrichment ratio (ER), and relative enrichment index (REI) values, as well as lab-scale water-leaching experiments predict that combustion residues of the studied power generating unit are safe for utilisation in construction, geotechnical, and even in agricultural sectors. Chemical characterisation and pre-treatment of ashes before utilisation are urgently required to predict any possible contamination. Regular scrutiny of emission control device, proper management of ash disposal, and frequent utilisation are the keys for clean energy generation. A bottomless chemical and physical autopsy of coal by power plants prior to utilisation is the primary task for sustainable energy generation from environmental aspect.

Carbones de la zona cundiboyacence fueron estudiados, con el fin de determinar la presencia y cuantificar los contenidos de elementos contaminantes como: cadmio (Cd), arsénico (As), plomo (Pb), selenio (Se) y mercurio (Hg), estos elementos son comparados con los índices de Clarke para carbones del mismo rango. Las muestras de carbón fueron tomadas de frentes de explotación activa y son analizadas mediante análisis próximos, petrográficos y por espectrometría de masas con plasma acoplado inductivamente (ICP-MS). Los resultados revelan que las muestras analizadas presentan contenidos promedio de metales como Pb (15,5 mg•kg-1), Se (16,5 mg•kg-1), Cd (0,55 mg•kg-1) y As (16,05 mg•kg-1) por encima del promedio mundial para carbones del mismo rango y sus concentraciones son mayores a los carbones de la zona norte carbonífera de Colombia, el contenido de Hg es bajo (< 0,08 mg•kg-1). El contenido de estos elementos genera preocupación ambiental ya que de acuerdo a la Agencia de Protección Ambiental de los Estados Unidos (EPA), el límite máximo permitido para el Se, Pb y Cd es de 0.05 mg•kg-1(ppm). Se sugiere realizar estudios específicos, que permitan la recuperación previa y/o utilización.
