In 1978 world mine production of copper decreased 3 percent to 8.21 million tons, with 14 countries each producing in excess of 100,000 tons. The United States was the leading producer and consumer of copper with 1.5 million tons of mine production and 2.5 million tons of primary plus old scrap consumption. Components of supply entering domestic consumption for 1969-78 excluding stock changes, were 67 percent from domestic mines, 21 percent from old scrap, and 12 percent from net imports. The import requirements in recent years were largely obtained from Canada, Chile, Peru, and Zambia. Almost all domestic mine output was from ores mined primarily for their copper content. In addition to copper these ores provided significant quantities of byproducts and coproducts such as gold, silver, molybdenum, selenium, tellurium, and rhenium. In addition to data on byproducts and coproducts, this Bureau of Mines report presents comprehensive data on copper including industry structure, uses, reserves-resources, technology, supply-demand relationships, strategic considerations, economic factors and problems, operating factors and problems, and outlook to 2000.
