对ＮＭＤ制备ＡＮＭＤ过程中歧化反应所产生的Ｍｎ２＋ 的再氧化行为进行了讨论和试验研究，以提高原料中锰的回收率。试验表明，不同的工艺条件对锰的回收率影响很大，控制适当的氧化条件可有效地提高锰回收率。
The reoxidation behavior of Mn2 + produced by disproportionation reaction during the preparation of ANMD by NMD was discussed and studied in order to improve the recovery rate of manganese in the feedstock. Experiments show that different process conditions have a great influence on the recovery rate of manganese. Controlling proper oxidation conditions can effectively increase the manganese recovery rate.
