摘要

Knowledge of the mineralogy of coal conversion wastes is essential science underlying either environmentally safe disposal or utilization of these wastes. Groundwater contamination is possible if these wastes are not disposed of properly. The fly ash samples from the Milton R. Young (MRY) and Coal Creek (CC) plants were dominantly noncrystalline glass. X-ray diffraction was used to identify the following crystalline phases in both samples: quartz, periclase, ferrite spinel, anhydrite and lime. In addition to the mineralogy studies, ash buried as much as twelve years ago at the mine site adjoining the MRY plant was collected as undisturbed core that incorporated the materials above and below the ash disposal horizon. The sealed core samples are being kept frozen in anticipation of a follow-up investigation of the changes in mineralogy and migration of species from the buried waste.
