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。

The content of manganese in rhodochrosite tailings (rhodochrosite tailing contains manganese gangue and manganese residue) is very low, even lower than 1% in manganese gangue. Most of them are discarded in tailings piles.
重庆锰矿原生矿石以菱锰矿为主,含锰8.08～27.96%、磷0.107～0.366%,而锰尾矿(本文中的锰尾矿包括锰矸石和锰渣)的含锰量低,锰矸石的锰含量甚至不足1%,大部分被长期丢弃在尾矿堆里,这些尾矿堆积如山占用土地,并会引起一系列的环境问题和危害。
