An Appraisal of Minerals Availability for 34 Commodities.
MISSING :300 pages
The Bureau of Mines has developed a policy support capability to perform availability analyses for 34 mineral commodities, which has required the development and integration of data bases, evaluation procedures, and analytic systems used to estimate mining and mineral processing costs and to perform commodity-wide economic analyses. Geologic, engineering, and economic evaluations of approximately 2,900 major mines, deposits, and mineral processing plants in market economy countries provide the basic data for the availability studies. The amounts and estimated extraction costs of known resources of each commodity are typically indicated via availability and capacity curves. This report includes an introduction, which details the methodologies and assumptions of the availability analyses, and 29 commodity chapters--aluminum through tungsten.
