Minerals in coal can be divided into two broad categories: (1) minerals that originated in the original coal-forming peat, termed syngenetic or primary minerals, and (2) diagenetic or secondary minerals, which were introduced into the coal, remobilized in the coal, or transformed from other minerals in the coal at any time after the original ...
Coals may contain as many as 76 of the 92 naturally occurring elements of the periodic table (); however, most of those elements usually are present in only trace amounts on the order of parts per million.Occasionally, some trace elements may be concentrated in a specific coal bed, which may make that bed a valuable resource for those elements …

Nonvolatile elements that were present in the parent coal either as mineral matter or trace elements are concentrated in the residual ash particulates as carbon, the primary component of coal, is combusted. Thus a coal containing 10% ash will produce ash with approximately an order of magnitude higher nonvolatile elemental concentration.

Around four-fifths of global primary energy comes from coal, oil, and gas. Over the coming decades, we must rapidly reduce this share by displacing them with low-carbon energy sources. ... Electricity is one component of total energy consumption – the other two being transport and heating. Globally, fossil fuels account for a much smaller ...
The burning of coal - especially in power plants and industrial processes - is a significant source of air pollution. Coal combustion emits sulphur dioxide (SO2) and nitrogen oxides (NOx), which are primary contributors to the formation of acid rain and ground-level ozone or smog.
Most of the coal in Mexico is concentrated in three widely separated regions. Coahuila on the northeast, Sonora on the northwest, and Oaxaca on the south …
