In this work, extraction of lead from Electrolytic Manganese Anode Mud (EMAM) by microwave coupled ultrasound was studied. The results showed that microwave roasting promoted the conversion of MnO₂ to Mn₂O₃ and Mn₃O₄, which greatly facilitated the subsequent leaching process of lead and the introduction of ultrasound effectively enhanced the leaching process. The leaching rate for lead from EMAM was arrived to 86.98% under the optimum conditions with the ammonium acetate concentration of 2 mol/L at 343 K and the stirring speed of 300 rpm for 60 min. With the introduction of specific power ultrasound, the leaching of lead was increased by about 10%. The microwave roasting combined with ultrasonic enhanced leaching can effectively for the reuse and reduction of EMAM which provides ideas for further investigation of lead pollution control and resource utilization in EMAM.

在这项工作中，研究了通过微波耦合超声从电解锰阳极泥（EMAM）中提取铅。结果表明，微波焙烧促进了MnO ₂转化为Mn ₂ O ₃和Mn ₃ O ₄的转化。极大地促进了铅的后续浸出过程，超声波的引入有效地增强了浸出过程。在最佳条件下，在343 K下乙酸铵浓度为2 mol / L，搅拌速度为300 rpm的情况下，从EMAM中铅的浸出率达到了86.98％。随着比功率超声的引入，铅的浸出增加了约10％。微波焙烧结合超声强化浸出可以有效地重复利用和减少EMAM，为进一步研究EMAM中铅污染控制和资源利用提供了思路。
