Abstract: As an important strategic mineral, germanium has an important application potential in emerging industries and national defense and military industries.With the increase in environmental protection and the adjustment of the industrial structure in my country, new requirements have been put forward for the extraction and deep processing of germanium resources.Studying the supply and demand situation of germanium resources is the basis for formulating relevant industrial development policies and plans.Based on global long-term data, this article uses the sectoral consumption method to quantitatively predict germanium demand in the next 25 years and analyzes the global supply and demand situation under the constraints of environmental protection.The authors think that the global demand for germanium resources will increase rapidly, and the demand in 2025, 2030 and 2035 is expected to be 198.5 tons, 258.1 tons and 308.6 tons, respectively.Restricted by environmental protection, the growth potential of global germanium supply is limited, and the shortage of supply will gradually become prominent from 2025.Globally, secondary recycling will further increase.It is estimated that 45% of global germanium will come from secondary recycling by 2035.Based on the above research, the authors believes that our country completes the transformation from a large germanium resource country to a resource-powered country, it is necessary for my country to introduce supporting policies in strengthening industry alliances, encouraging R&D investment, and supporting secondary recycling.
