copper pyrometallurgical process flowchart
Production process
After pyrometallurgical smelting (or a multi-step recycling process) and a downstream electrolytic refining process, the copper is ready for further use in its purest form, as a high-quality cathode. These cathodes, which have a copper content of more than 99.99 %, are first melted down in a carefully monitored process and then cast ...
