grinding media). In 1977, the primary copper industry purchased 121trillion Btu of energy, or around 85 miIlion Btu per short ton of hode copper produced.] This compares to around 15 million Btu/ton for iron mining and steel production, 24 million Btu/ton for lead production, and 64 million Btu/ton for zinc,
All aspects of copper production require energy, whether i n the form of electricity, explosives, or hydrocarbon fuels (diesel, gasoline, natural gas, fuel oil, coal, coke), or as the energy equivalent of materials consumed (e. g., chemicals and steel grinding media). In 1977, the primary copper industry purchased 121trillion Btu of energy, or around 85 miIlion Btu per short ton of hode ...
Copper production in Montana was also spurred by drop in copper production outside the United States in the early 1880's. Copper production in Great Britain dropped from 16,000 tons in 1860 to 3,800 tons in 1880. Chile's production decreased from 50,000 tons to 38,000 tons. There was an increased need for domestic copper.
