Primary Copper Smelting General1 Copper ore is produced in 13 states. In , Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the megagrams (Mg) ( millon tons) of ore produced in Copper is produced in the U. S. primarily by pyrometallurgical smelting. In alloying, copper-containing scrap is charged to a melting furnace along with 1 or more other metals such as tin, zinc, silver, lead, aluminum, or nickel. Fluxes are added to remove impurities and to protect the melt against oxidation by air. Air or pure oxygen may be blown through the melt to 11/94 Metallurgical Industry ©Air Products and Chemicals, Inc., Pub.

of the rationale for regulation, the technological controls, and the impact of those controls on do-mestic competitiveness. Further analysis of envi-ronmental regulation and its impact on the U.S. copper industry may be found in chapter AIR QUALITY Pollutants of Concern and Their Regulation Uncontrolled copper smelting processes emit. Some Observations - •Source: ICSG, Copper Bulletin 8 •South America is the most important copper mining region •More than 35% of world copper concentrate originated in South America •But only 13% of world copper concentrate was smelted in South America •Chile is the world’s largest copper mine producer •China is the world’s largest smelting country. EPA/ EMISSION FACTORS AND EMISSION SOURCE INFORMATION FOR PRIMARY AND SECONDARY COPPER SMELTERS by G.E. Umlauf and L.G. Wayne Pacific Environmental Services, Inc. 14th Street Santa Monica, California Contract No. Task Order No. 3 EPA Project Officer: Arch McQueen Prepared for . This action promulgates national emission standards for hazardous air pollutants (NESHAP) for primary copper smelting. Primary copper smelters can potentially emit significant amounts of certain toxic metals listed as hazardous air pollutants (HAP) in Clean Air Act (CAA) section (b)(1). These.
As technology has improved over recent years, more and more countries have applied the technique in copper ore smelting, including the US, Chile, Canada, Australia, Mexico and Peru. The classification of copper; 1. Morphological classification in nature; Native copper: copper content is over 99% (limited reserves). Copper oxide ore: limited. To determine whether your facility is regulated by this action, you should examine the applicability criteria in 40 CFR of subpart EEEEEE (National Emission Standards for Hazardous Air Pollutants (NESHAP) for Primary Copper Smelting Area Sources) or 40 CFR of subpart FFFFFF (NESHAP for Secondary Copper Smelting Area Sources). Copper in the USA: Bright Future Glorious Past Copper Producers. At the beginning of copper's flow through the economy are the mining companies, which process vast quantities of low-grade ore, mostly from open-pit mines in order to produce copper. Approximately two tons of overburden must be removed along with each ton of copper ore. The Environmental Protection Agency (EPA) is failing to protect communities and the environment from toxic air pollution emitted by copper smelters, environmental groups argued today. The U.S. Court of Appeals for the District of Columbia heard oral arguments in a case (Docket # ) challenging EPA's inadequate regulations for controlling toxic air .
