Abstract
This article describes quality-control work at Phelps Dodge, undertaken as part of ISO 9003 certification, to better identify and prevent the contamination of copper cathodes by bismuth. It also overviews the implementation of a production control system as well as associated training designed to minimize the possibility of bismuth-contaminated copper progressing beyond the cathode stage to other areas of manufacturing or distribution.
