Abstract A process for treating low-grade anode mud in order to recover noble metals (gold and silver) from copper or lead anode mud features three-stage smelting, which includes reduction smelting in anode mud smelting furnace, primary oxidizing blow smelting in low-grade noble lead blow smelting furance and deeply oxidizing refining of high-grade noble lead. Its advantages are short production period, low energy consumption, high recovery rate of Bi and Te and low production cost.
