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
Highlights
Coal serves as source of energy resources and as source of organic compounds of 21th century
Nowadays more than 90 percent of Mongolian power electricity and heat energy are produced by using of coal resources and coal is the main and reliable source of energy throughout in all aimags and soums of Mongolia
The results show that most of rare earth elements in the ash samples have contents lying in the ranges for most coals
Summary
Coal serves as source of energy resources and as source of organic compounds of 21th century. At the same time coal ash is reliable source of rare earth and dispersal elements. Coal deposits are beginning to evaluated by their contents of rare earth and dispersal elements because of their needs in modern industrial branches. Investigation of coal mineral matter, chemical composition and trace elements in ash is important task.
