NTIS: PB 192 181 :
This report compares the cost of operating supplies and parts and materials for repair and maintenance used by the U.S. copper industry in 1958 and 1963. Mining, beneficiation, and hydrometallurgical activities only are included. This evaluation brings together for the first time detailed cost data for different years. It provides a better understanding of the impact on the supplying industries of the changing demands for inputs and the interrelationship of other sectors of the national economy. It also permits discussion of the changing pattern in the demand for inputs as a result of the gradual adoption of new technology and its effects on operating practices. It allows broader implications to be drawn about rates of technologic progress in mining activities.
