Study of rare earth elements in coal ash from Khartarvagatai coal deposit

Abstract

Have been investigated the mineral matter and chemical composition of ash from the Khartarvagatai coal deposite by X-ray fluorescence (XRF) and atomic absorption spectroscopy (AAS) methods. In the ash of this coal have revealed trace elements like Се, Th, Be, La, Nd, Y, As. These elements come from mineral gasparite that present in raw coal. All diffraction patterns were analyzed by full-profile Rietveld refinements, using the software package WinPLOTR.DOI: http://dx.doi.org/10.5564/mjc.v12i0.168 Mongolian Journal of Chemistry Vol.12 2011: 35-37
