| General |
The plant’s smelter was modernized in 1974 to meet
Clean Air Act standards The smelter is the only one in the United States to achieve International Organization for Standardization (ISO) 9001:2000 certification. In addition to copper concentrates, the smelter also recycles inorganic metal-bearing waste typically produced by high technology industries, extending the useful life of valuable metals and reducing disposal of metal-bearing waste in landfills. Copper and other precious metals are extracted during this process. In addition, the smelter produces by-product sulfuric acid. |
