Determination of Minerals in Coal by Methods Based on the Recalculation of the Bulk chemical Analyses

Original language description

Chemical Quantitative Phase Analysis (CQPA) suggested originally for magmatic rocks (Klika et al., 1986) now is tested for the quantitative mineral determination of coal. This method is based on the optimization procedure. For the evaluation of mineral contents, 5 coal samples were selected and the following analytical data were determined: a) chemical analyses (XRF, titrimetric and gravimetric analytical methods), b) qualitative mineral composition (the X-ray powder diffraction, SEM-EDX and image analyses), c) crystallochemical formulae of minerals. The calculated percentages of minerals obtained by CQPA were compared with calculated percentages of minerals obtained by Raask's method. Simple statistical evaluation showed that calculation of minerals by CQPA program delivers considerable improvement of results.
