✦ Synopsis
Zonguldak bituminous coal from a washery flotation plant feed in Turkey was anaiysed using X-ray diffraction (XRD). The aim was to determine qualitatively as well as semi-quantitatively its clay mineral content. For qualitative determination of the clay minerals, pre-treatment of the coal samples was carried out to remove organic matter before XRD analysis. The presence of three clay minerals (i.e. kaoiinite, iiiite and chlorite) was verified by XRD analysis on coal samples after cool oxygen plasma oxidation to yield low-temperature ash for the analysis. For semiquantitative analysis, Biscaye's method for sediments was used. Using this method a semi-quantitative result was obtained for clay minerals, with kaoiinite SO%, illite 30% and chlorite 20%.
