Abstract: As an important metal mineral, manganese is widely used in metallurgy, chemical and national defense industries and other fields. The global manganese resources are characterized by extremely unbalanced distribution, highly concentrated production capacity and serious contradiction between supply and demand. However, China's manganese resources are widely distributed but lack of reserves, low grade and poor quality, high dependence on foreign countries, and imperfect resource guarantee system. In recent years, China's manganese mine industry has developed rapidly. China has become the world's largest consumer of manganese resources. With the growth of the new energy market, the contradiction between supply and demand of manganese resources in China will further increase in the future. Based on the current situation that manganese mine is still in short supply and in great demand in China, in order to ensure the strategic safety of national manganese resources and promote the sustainable development of China's manganese industry, this paper puts forward suggestions for sustainable development such as formulating long-term supply plans, strengthening overseas layout, promoting production capacity cooperation, and establishing a diversified security system.
