| Abstract: | In this paper, the sulfur distribution regularities in different particle size fractions and density classes of Huaheng high sulfur coal were studied by determining and analysing every kind of sulfur content. Then by using Design Expert software, the mathematical model of pyritic sulfur distribution regularities was set up. The study shows that this mathematical model can be used to figure out relatively accurate prediction results and provide a new method to determine the comminution size for liberating the pyritic in the high sulfur coal. |
