Abstract: At present, the global distribution of manganese ore resources are unevenly distributed and the production capacity is highly concentrated. Based on the overview of international and China's manganese ore resources, and in response to the characteristics of China's wide distribution of manganese ore resources, low grade, poor technical processing performance, and high external dependence on high-quality manganese ore, the research progress of manganese ore beneficiation technology was summarized. The current situation of manganese ore research and application from three different beneficiation processes such as traditional beneficiation, reduction leaching, and combined roasting method, were reviewed. The technological problems in manganese ore beneficiation were analyzed, and the development trend of high efficiency, clean and economic manganese ore beneficiation technology has been prospected. The research provides a technological reference for the resource utilization of manganese ore.
