| Abstract: | As and Sb in black copper sludge was leached at high pH values in the sodium sulfide solution. By maintaining strong alkaline conditions, As and Sb could be separated from the leaching solution using hydrogen peroxide as oxidant, and sodium arsenate and sodium pyroantimonate were obtained. Leach residue can return to the main smelting process. |

| Keywords: | black copper sludge leaching sodium arsenate sodium pyroantimonate |
