Throughout most of the Appalachian coal fields, abandoned deep mines are considered to be the principal source of acid mine drainage pollution. The reasons for this perception are based on the sheer number of abandoned deep mines, the number of very large acreage abandoned mines and the fact that nearly all older mines were developed to the rise to promote gravity drainage. .

· In coal preparation, screening machines serve two purposes: sizing and media recovery. Oftentimes, the initial screening is performed by a scalping screen loed outside the plant. This prevents the screens inside the plant from becoming overloaded. The deslime screens make the next cut and most prep plants size to minus 1 mm. The media, or magnetite, is .
