The literature search on the chemistry and environmental behavior of trace elements in coal cleaning wastes has been completed, and an interpretive report of the findings from the literature has been written. Techniques and methods for analyzing trace elements and minerals in coals and coal cleaning wastes have been developed and are documented in this report. Standard coal and ash samples were used to establish the precision and accuracy of these methods. High-sulfur coal-waste materials have been collected from three coal cleaning plants in the Illinois Basin, and cleaning wastes from a low-sulfur coal have also been collected. Analytical studies of the trace elements and minerals in these wastes are progressing, and investigations of the effects of weathering and leaching on the trace elements in the refuse have been started.
