本课题针对上述问题，采用酸浸贫菱锰矿制备硫酸锰进而制备生成四氧化三锰的工艺路线。
In view of the problems above, this paper put forward a new craft route, which was preparing manganous sulfate from rhodochrosite by acid-leaching as raw material to get manganic manganous oxide.

菱锰矿
菱锰矿是碳酸盐矿物，它常含有铁、钙，锌等元素。并且这些元素往往会取代了锰。因此，纯菱锰矿很少见。菱锰矿也是生产铁锰合金的锰的来源。它们通常为粒状、块状或肾状，红色，氧化后表面呈褐黑色。具有玻璃光泽。晶粒大、透明色美者可作宝石。颗粒细小、半透明的集合体则可作玉雕材料。
