The mineral wastes produced by coal cleaning contain an abundance of toxic or potentially harmful trace elements. Although it has been well established that many of these toxic elements are present in the drainages from coal waste dumps, little is known about the quantities released into the environment from this source. The objectives of an ongoing research program at the Los Alamos Scientific Laboratory are to assess the nature and magnitude of the trace elements in the effluents from coal refuse materials, and to develop appropriate environmental control technologies as needed. Recent experimental results concerning the chemistry and aqueous leaching behavior of the trace elements in high sulfur coal cleaning wastes are presented. The emphasis is on the interpretation of the experimental data that has led to the identification of the trace elements in coal refuse effluents that are consistently present in unacceptable quantities, and the development of environmental control strategies designed to abate or mitigate the problems of environmental control strategies designed to abate or mitigate the problems of environmental concern that have resulted from these refuse drainages.
