In the process of copper smelting, a large amount of copper slag is produced and gold and silver are discharged along with copper slag. In order to reasonably recover gold, silver and copper from copper slag, a vortex dilution method was proposed. The molten copper slag was used as raw material, the gold, silver and copper in copper slag were recovered through the vortex dilution process, and the diluted slag was further reduced to produce copper-containing molten iron, which could finally be prepared into wear-resistant cast iron or copper-containing antimicrobial stainless steel. The results showed that Fe3O4 in copper slag was reduced to FeO by FeS and then FeO combined with SiO2 to form Fe2SiO4. After vortex dilution, the recovery rates of gold, silver and copper reached 99.44%, 93.97% and 93.14%, respectively. The content of Fe3O4 and Cu in diluted slag were 1.53% and 0.61%, respectively. The copper-containing molten iron was obtained from the diluted copper slag by vortex reduction and then used to produce the wear-resistant cast iron, the element composition of which could meet the requirements of national standard of high chromium wear-resistant cast iron.
