Coal, containing all the elements that are present in nature and more than 200 minerals, has
a complex chemical structure, making it one of the most complex geological materials …

Coal is a complex geologic material composed mainly of organic matter and mineral matter,
the latter including minerals, poorly crystalline mineraloids, and elements associated with …

The material classed as “mineral matter” in coal embraces crystalline mineral materials as
well as a range of inorganic elements that occur in non-crystalline form. This review outlines …

Coal-based power generation produces over 750Mt of coal ash per year globally, but under
50% of world production is utilised. Large amounts of fly ash are either stored temporarily in …

The material described as “mineral matter” in coal encompasses dissolved salts in the pore
water and inorganic elements associated with the organic compounds, as well as discrete …

Throughout the world, coal is responsible for generating approximately 38% of power. Coal
ash, a waste product, generated from the combustion of coal, consists of fly ash, bottom ash …

This preliminary study focuses on the determination and comparison of major and trace
element concentrations in feed coals from ten Turkish coal-fired power plants (Cayirhan …

Permian coals of the southern hemisphere are generally considered to contain lower
concentrations of sulfides, halogens, and trace elements when compared to northern …

This study focuses on ascertaining controlling factors and differences on mineralogical and
elemental contents for reconstructing palaeoenvironmental conditions of both seams …

Feed-coals used in some Canadian power plants were examined for their mineralogical and
elemental composition. The mode of occurrence of elements (organic/minerals) in these …
