Energy Consumption in Domestic Primary Copper Production.
NTIS: PB 252 493 :22 pages
Energy consumption in domestic copper production has increased nearly 60 percent in the last 10 years, reaching approximately 175 trillion btu in 1973. Energy required to produce 1 pound of copper rose from nearly 41,000 btu in 1963 to nearly 50,000 btu in 1973. Production from lower grade ores and strict pollution control regulations have contributed to this increase. Each stage of copper production has been analyzed to determine total energy consumed, energy mix required, cost of the energy, and recent or proposed changes in operations which may affect the consumption of energy by the copper industry. Data have been gathered from a recent Bureau of Mines canvass of the industry, from visits to copper operations, and from conversations with copper industry officials.
