The purpose of this study, contained in nine separate volumes, was to provide basic data on energy consumption in industry and to identify opportunities for energy conservation. Each volume is organized into 4 sections: section 1 is an introduction, section 2 describes the methodology employed in the study, section 3 contains executive summary tables of energy consumption data for each of the nine industries examined, and section 4 analyzes the data collected for one specific industry. Volume 4 describes the processes used and the energy consumed in the production of refined primary copper. The energy consumed is found to be distributed as follows: Mining and ore preparation, 60.7 MMBTU/ton of copper (54.3%); smelting, 45.6 MMBTU/ton of copper (40.8%); and refining, 5.5 MMBTU/ton of copper (4.9%). There is a strong dependence on natural gas and electricity, the natural gas being used heavily in smelting and the electricity in the ore beneficiation steps. Using primary fuel resource costs, the cost of energy in the production of one ton of primary copper is calculated. It is found that for one ton of primary copper the cost is $43.94. Based on an average U.S. price in the first half of 1970 of $1148/ton, the energy cost represents about 3.8% of the value of shipments. Several items of particular interest are discussed, including developments in smelting techniques, developments in copper refining, development of hydrometallurgical processes, and secondary copper (copper produced from scrap materials).
