Distribution characteristics of trace elements in coal of Inner Mongolia Baiyinhua coalfield

In terms of the characteristics of trace element content and its distribution in coal,the analysis of trace ele- ments in coal testing was carried out in Baiyinhua coalfield,China. Trace elements,rare earth elements were collected from 50 samples of four mining areas and three layers in Baiyinhua coalfield. The study focuses on analyzing coal mac- eral characteristics,F,Cl,arsenic in coal and other harmful trace elements distribution,and the enrichment of 24 kinds of trace elements including Sb,Ag,Ge,Be,CO in the coal mining areas. Also,the existing state of germanium in coal and coal formation environment was analyzed. The results show a high content of As in Baiyinhua coalfield,belonging to super high arsenic coal. Trace elements such as Co,Cr,Ge,Ca,Li,V,La,Ce,Nd,Th and U,etc. are obvious in No. 2 coal mine of Baiyinhua coalfield. Ga and Ge contents were found to reach industrial grades in many locations;Ger- manium was bound to organic matter in Baiyinhua coal;Germanium element was easy to be enriched in reducing envi- ronment. From the boron’s source trace in the coal of Baiyinhua coalfield and the indication of sedimentary environ- ment,the coal formation environment was a fresh water and brackish water environment.
