Effects of minerals on coal beneficiation. Final report

In order to meet future energy needs of the nation while still maintaining the environment and reducing the nation's dependence upon foreign sources, the US Department of Energy has been performing a large research effort directed towards developing a major state-of-the-art information and technology base concerning the exploitation of solid fossil fuels. As part of this effort, the subject research project has examined a major commercial coal seam (The Pittsburgh Coal) to determine the mineralogical-maceral associations which occur and to detect the changes which occur during conventional size and specific gravity cleaning processes. The data and information obtained, when compared with the results of similar studies to be performed with other coals, could define association trends and ultimately lead to more effective and efficient coal cleaning processes and procedures.
