America's dependence on strategic minerals.
Pres Soc Min Eng AIME 113th Ann Mtg Los Angeles California Feb 26- 1984 Mar; :1-29
This paper illustrates the degree of U.S. dependence on domestically produced and imported strategic materials, the source of imports on a geographical basis, and the trends that may be foreseen for the remainder of this decade in terms of the future supply of these materials. Strategic materials were defined and 20 were selected for an examination of recent trends in import dependence and the outlook for a reversal in the trend. For the minerals and metals for which the United States is over 75 pct dependent, the major source countries are oftentimes the Republic of South Africa, the U.S.S.R., and the developing countries of Africa, Asia, and South America. Based on reserves and resource estimates, it appears that these countries will continue to be major suppliers of strategic materials for the foreseeable future.
