to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety.

Mining In simple terms, mining involves breaking apart in-situ materials and hauling the broken materials out of the mine, while ensuring the health and safety of miners and the economic viability of the operation. A relentless search has been under way since the early l900s for new and innovative mining technologies that would improve health and safety and increase productivity.

Technology needs in physical separation processes are focused mainly on minimizing entrained water in disposable solids, devising improved magnetic and electrical separators, developing better ore-sorting methods, and investigating selective flocculation applications. Although flotation is a well developed technology, the mining industry would benefit from the availability of more versatile and economic flotation reagents, on-stream analyses, and new cell configurations.

Research is also needed to further develop and optimize treatment technologies for acid rock drainage, such as biologic reduction, and to address issues associated with the creation of pit lakes. Improved technologies are also nec essary for managing nonacidic wastewaters, including the development of effective, low-cost techniques for remov ing low concentrations of elements, such as selenium, from large volume flows and removing nitrates from wastewater discharges.

Department of Energy and receives guidance from the National Mining Association and its Technology Committee. The NRC's Committee on Technologies for the Mining Industries recognizes that the research and technology needs of the mining industry draw upon many disciplines, ranging from basic sciences to applied health, safety, and environmental sciences.
