A New Copper Scrap Fire-Refining Concept for

2021-11-22 · Arsenic monitoring is a critical issue in the copper-making industry, and its removal at the fire-refining stage is important. However, arsenic is poorly removed in the traditional fire-refining practices. A new “As enrichment—targeted oxidation—slag modifying” process is proposed and experimentally studied in this work. The results showed: (1), arsenic can be
