The rank classification of Nigerian coals consists of 39% bituminous, 49% subbituminous, and 12% lignite [5], currently utilized in cement, iron and steel manufacturing. However, the contribution of coal to Nigeria's electricity generation remains insignificant [3]. As a result, Nigeria's drive for industrialisation has been stunted by the ...

Physico-Chemical Characterization and Speciation of ...

Studies of physico-chemical characterization, and chemical speciation of sulphur of seven Nigerian coal samples have been undertaken. The seven coal samples originated from South-east, North-central and North-east of Nigeria where there are proven economic deposits of this mineral. Moisture content, bulk density, percentage ash and loss of mass on ignition of all the coal samples were determined.

Proximate and Ultimate Analysis | Mining | SGS

SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference). We determine each element through chemical analysis and express it as a percentage of the total mass of the original coal or coke sample.
