Metal Organic and Inorganic Affinities in Strippable Fort Union Formation Coal. Volume 1.
For Reference Only At Bureau Libraries :52 pages
The methodology for describing the geochemistry of elements in a coal seam was developed and has been applied to the rosebud coal seam, an economically important member of the subbituminous coals of the Fort Union Formation in eastern Montana. The method development involved a detailed study of two popular techniques for determining the metal geochemistry of coal, namely, whole coal analyses and coal physical fractionation. The mathematically contrived element associations and the element concentration trends in the float and sink fractions are considered to lead to only qualitative conclusions concerning the chemical associations of the elements in coals. Additionally, the processes taking place with the coal during low-temperature ashing in an oxygen plasma were experimentally investigated and shown to be of sufficient extent that the use of such low-temperature ash for deciphering element geochemistry is questionable. Volume 1 of this two-volume report presents a description of the study.
