Abstract

The phase composition of raw coal in Liupanshui Miluo area was analyzed by XRD, and the Hg content of raw coal was measured by atomic fluorescence spectrometer, and discussed the occurrence of Hg in the coal. The results showed that the Hg content in the coal increased with the sulfur, density, size and ash increasing. When the density exceeded 1.8g/cm3, the maximum Hg content reached to be 1.68 ppm. At the same time the maximum sulfur and ash also measured respectively, it is 2.68% and 45.47%. The ash and sulfur in coal had high correlations with the content of Hg in coal, which indicated that Hg had certain inorganic affinity. The density distribution model of mercury in Miluo coal was obtained.
