| Abstract: |
| A novel technology of soda--lead concentrates reverberatory furnace smelting is put forward according to the characteristics of copper dross with low sulfur and high copper content. The results show that the recovery of lead, gold and silver increased by 10.75%, 19.86% and 12.82% respectively; copper in the matte reached up to more than 28%; the output of As--Cu--Pb alloy was reduced obviously; the operating condition of the furnace was also improved. |
