X-RAY DIFFRACTION (XRD) ANALYSES OF THAR, SONDA AND METING-JHIMPIR COALFIELDS, SINDH

Abstract

X-ray powder diffraction (XRD) is an instrumental technique used to identify unknown/various minerals. Rigaku X-ray diffractometer was used to record X-ray intensities scatters of the coal samples, collected from various coalfields of Sindh. Cu (K-alpha) radiations were used as X-ray source. These scatters shows that minerlogically the Sindh coals contain quartz and kaolinite as the dominant mineral phases with subordinate amount of calcite, dolomite, muscovite and illite. These minerals may have significance influence on the boiler of the power plant may also cause environmental degradation by producing emission of SO2, CO2.
