The future of nonfuel minerals in the US and world economy, input- output projections 1980-2030.

Reports on a large-scale economic research project directed at improving the understanding of the interdependence between economic growth and the role of materials in production. Demand for 26 minerals through to the year 2030 is forecast, under alternative assumptions. Detailed descriptions of the input-output techniques used for the forecasts are provided. A total requirement matrix of minerals for 1972 and 2000 is listed. Fuels were not included, nor were construction minerals or industrial gases or synthetic industrial diamonds. The minerals covered amount to 90% of the dollar value of the U.S. mining industry in 1972. -P.M.Townroe
