对从天然氧化锰矿（ＮＭＤ）活化制备得到的活性放电锰（ＡＮＭＤ）的重质化加工技术进行了讨论和试验研究，试验确定了重质化工艺适宜的工艺条件，产品的视比重可达１．８ｇ／ｃｍ ３ 以上，活性氧化锰的放电性能可达到或接近电解二氧化锰的质量标准。
The reformation process of active discharge manganese (ANMD) prepared from the activation of natural manganese oxide (NMD) was discussed and experimentally studied. The suitable process conditions of the heavy chemical process were determined and the apparent specific gravity of the product was up to 1 .8g / cm 3 above, the discharge capacity of activated manganese oxide can reach or close to the quality standard electrolytic manganese dioxide.
