Method for producing MnO through reducing roasting of MnO ore by utilizing wood chips

The invention belongs to the fields of metallurgy and chemical engineering, and particularly relates to a method for producing MnO through the reducing roasting of MnO ore by utilizing wood chips. According to the method, the wood chips are adopted as a reductant, so that the MnO ore can be reduced into MnO under the condition of low temperature (300-500 DEG C); consequently, the production energyconsumption can be greatly reduced and the service life of equipment can be prolonged; the method is simple in process, convenient to operate, low in roasting temperature, and high in efficiency of the conversion from high-valent Mn to bivalent Mn; the cost of the reducing roasting of the MnO ore can be remarkably reduced; and furthermore, qualified MnO can be produced by adopting the method. 本发明属于冶金和化工领域，具体涉及种利用木屑还原焙烧氧化锰矿制取氧化锰的方法；该方法采用木屑作为还原剂，能使氧化锰矿在低温（300～500℃）条件下被木屑还原成MnO，从而大大降低了生产能耗，延长设备使用寿命，该方法工艺简单，操作方便、焙烧温度低、能耗低、高价锰到二价锰的转化效率高，可显著降低氧化锰矿石还原焙烧的成本，而且采用该方法能生产得到质量合格的氧化锰。
