Abstract：The process of fluidized low-temperature reduction manganese oxide ore developed by the Institute of Process Engineering, Chinese Academy of Sciences was introduced.The results show that compared with the traditional high-temperature reduction process, only 60％unit coal is consumed.The output of unit production line can reach 600 t/d.Manganese oxide ore containing total Fe less than 15％and crystal water less than 18％can be used in this process.The reduction reaction is improved by lower temperature and less side reaction.The leaching reaction is improved by lower impurity leaching rate.The tail gas meets national standards without desulfurization and denitration process.
