我国氧化锰矿主要分布在北纬２３°带内，带内氧化锰矿分布广，氧化深度大，忆矿石品位富，矿床规模大。氧化锰矿形成的条件为：带内有丰富的原生沉积锰矿层或矿胚层；年积雨量充沛；年积温量高；热带雨林广布，微生物引起的生物化学作用强烈。氧化锰矿主要分布在向斜构造和地貌洼地内。
China’s manganese oxide ore is mainly distributed in the 23 ° north latitude belt, with a wide distribution of oxidation of manganese ore, oxidation depth, Yi ore grade rich, large-scale deposits. Manganese oxide formation conditions are: the belt is rich in primary deposits of manganese ore or ore layer; annual rainfall is abundant; annual accumulated temperature is high; tropical rain forest is widespread, microbial biochemistry caused by a strong role. Manganese oxide ore is mainly distributed in the syncline structure and landform depression.
