Abstract

CHEMICAL AND MINERAL STRUCTURE OF AN ANORGANIC MINERAL SUBSTANCE OCCURRING IN BITUMINOUS COALThe author examined the chemical, and mineral properties of an anorganic mineral substance occurring in the coking coals from seams 12A (626?) and 14 (628?) of, the May 1st colliery. As basis for his examinations of the discussed substance the author chosen the chemical and mineral composition of the ashes obtained by burning the coal at 350-400°C. The ash obtained at these temperatures is well suited for microscopic investigations; therefore, the author examined chemically the ashes of these coal samples both wholesale and by phases (Analyses I and II; and Table l). These chemical analyses he then calculated in terms of mineral components, macroscopically determined (Table 2).
