The action mechanism of microbiological oxidation of rhodochrosite has been investigated by batch operation.
采用间断操作的试验方法，探讨了碳酸锰矿石微生物氧化过程的作用机制。

The former, distributed in broad area comparatively, is originated from the primary rhodochrosite of sub-weathering, and occurs as banded extension;
前者在区域上分布相对较广，是由原生菱锰矿床经次生风化而成，呈带状延伸；
