Bureau of Mines Research '79. A Summary of Significant Results in Mining, Metallurgy, and Mineral Economics.
Minerals are vital to the economic well-being of our society. The demand for the mineral raw materials is rising rapidly, creating unprecedented worldwide competition. It is now important to recover minerals from lower grade ores, recycle mineral materials, and substitute abundant materials for scarce ones. We are aware of the environmental impact of mineral production, and are determined to minimize its adverse effects. The health and safety of workers in the mineral industries continue to be of prime importance. Social, political, or economic situations in distant countries can affect our supplies of essential mineral commodities. The Bureau of Mines recognized that such complex issues require rapid, comprehensive analysis of mineral-related issues and policies, along with research and development programs that are responsive and efficiently conducted. The internal organization of the Bureau was restructured to combine this type of analysis with an ongoing program planning effort more responsive to today's rapid change. Research 79, the ninth in this annual series, highlights significant research conducted during the past year under contract or at the Bureau's research facilities throughout the United States. A directory and a listing of publications authored by Bureau personnel in the past 3 years appear at the end of the publication.
