摘　　要：针对广西高品位、低活性的天然氧化锰矿，采用活化工艺进行加工以提高其放电性能，取得了较好的效果。文中讨论了活化工艺的焙烧过程，试验确定其适宜的焙烧条件为：温度７１０℃，时间２ｈ。The natural manganese (NMD) ore originated from Guangxi,which has high manganese grade and low discharging property,was activated to improve the discharging property of the product ANMD (activated natural manganese dioxide).The roasting and transforming process of manganese dioxde were discussed in this paper.The experiments showed that obtained results are good and proper roasting conditions were temperature of 710℃ and time of 120min.
