01/03/1993· Clay minerals generally account for 60-70% by weight of average low temper- ature ash and are highly dispersed into carboniferous bands between layers of coal (Renton, 1982). The most frequent type of clays in coal are kaolinite and illite, the latter altering to chlorite at higher degree of metamophism (Diesel and Ottler, 1975; Falcon, 1978).

Mineral Matter in Coal

In high rank coal, mixed-layer clay minerals, dickite and chlorite formed during diagensis may occur. The clay minerals in coal occur mainly as dispersed inclusions such as grains, nodular masses, lenticles, and bands as well. They can also fill in cell cavities and cleats. Usually the partings in coal seam consist mainly of clay minerals.

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

analyzed. Clay mineral grains from the Illinois #6 coal sample were examined for Cr content; this element was detected at up to 950 ppm in half of the grains analyzed. These results show the heterogeneous distribution of these trace metals in coal mineral grains. Similar results are evident for Pittsburgh #8 bituminous coal.

Chapter 7 COAL

Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O). Most of the world's coal exists in the northern hemisphere. The United States, former Soviet Union ...

Ash content of coal is the non-combustible residue left after coal is burnt. It represents the bulk mineral matter after carbon, oxygen, sulfur and water (including from clays) has been driven off during combustion. Analysis is fairly straightforward, with the coal thoroughly burnt and the ash material expressed as a percentage of the original weight. It can also give an indication about the ...
