| Abstract: | The paper generally describes distribution of harmful elements in coal and its occurrence appearance in coal ,gives an analysis on the mode for the elements to be separated out during coal processing and particularly demonstrates the harm that the elements such as Hg , As and Se do to environment and human health. Discussion is also made in the paper on the state-of -arts of research work for control of the influence of harmful micro-elements through coal preparation and dedusting after coal combustion. |
