某放电氧化锰矿床,属氧化残留锰帽类型,系由某浅海相沉积碳酸锰矿床浅部风化而成,赋存于中奥陶统磨刀溪组下部粘土页岩与炭质页岩之间。该类型矿床在湘中地区较为发育,是我国目前发现的锰矿床新的成矿地质时期——奥陶纪的典型矿床。该矿床先后由勘探部门对其浅部次生氧化锰及深部原生碳酸锰矿体进行了初步评价。但欠缺的是,对于可作为国家急需放电锰粉及冶金子砂原料的氧化锰矿体,仅进行了粗略的地表工作,有关矿体形态、质量、氧化深度及其变化特征尚了解不够,给矿山开采带来较大困难,因此,上述疑点也就成为矿山开采氧化锰矿石时生产勘探中必须解决的课题。
A discharged manganese oxide deposit belongs to the type of redox manganese oxide cap and is formed by the shallow weathering of a shallow marine sedimentary carbonate manganese deposit and occurs between the lower clay shale and carbonaceous shale of the Middle Ordovician Shadoguxi Formation . This kind of deposit is relatively developed in Central Hunan Province, and is a typical deposit of Ordovician, a new stage of metallogenic geology of the manganese deposit currently discovered in China. The deposit was successively evaluated by the exploration department for its shallow secondary manganese oxide and deep primary manganese carbonate ore body. However, what is lacking is that only rough surface work is carried out for the manganese oxide ore body, which can be used as the raw material for the discharge of manganese powder and metallurgical sub-sand in the country. There is not enough understanding about the ore body morphology, quality, oxidation depth and its variation characteristics, Mining has brought greater difficulties, therefore, these doubts will also become a mine exploration of manganese ore production exploration must solve the issue.
