The purpose of this project is to investigate in the laboratory the options available for treating high-sulfur coal refuse materials either at the preparation plant or during disposal to prevent or reduce subsequent releases of environmentally harmful trace elements during waste dump weathering and leaching. Such control technology might include (1) chemical or physical processing to remove the undesirable elements from the refuse or treating the refuse materials to immobilize these elements; (2) applying neutralizing agents, adsorbents, or sealants at the refuse dump site, and burying, grading, and compacting the waste materials to control the flow of water and air through refuse piles; or (3) treating the contaminated drainage itself to reduce the contaminant concentration to environmentally acceptable levels. These three basic environmental control categories are discussed in this presentation.
