Abstract

This study first analyzed the phase composition of Dahebian coal mine by XRD, then do the experiment of screening, float and sink test, following the Hg content of coal was determined by atomic fluorescence spectrophotometer, and the regularities of distribution of Hg was studied. The results showed that the Hg content of the coal increased with the ash, density increasing, which indicated that Hg had a certain inorganic affinity. There is a significant correlation between Hg content and average density, when the density exceeded 1.8g/cm3, the maximum Hg content reached to be 0.97 ppm. At the same time the maximum sulfur and ash also measured respectively, it is 0.46% and 56.32%.
