NMD活化制备ANMD工艺研究(3)——浸出液中Mn^(2+)的氧化回收

Study on The Preparation of ANMD from NMD (3) ——Oxidation and Recovery of Mn^(2+) in the Leaching Solution

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 oxidation of the leaching product-Mn 2+ in the activation process of natural manganese ore was discussed.The experiments was undertaken to increase the recovery of manganese.The experimental results showed that different conditions would influence on the recovery of manganese.The recovery of manganese could be raised effectively by controling suitable conditions.
