美国政府：提议将铜、硅、银等列入关键矿产清单

Core Viewpoint - The U.S. government proposed to include copper, silicon, silver, and other minerals in the 2025 critical mineral list due to their importance to the economy and national security [1][4]. Group 1: Proposed Minerals - The draft list includes six newly proposed minerals: copper, potassium, silicon, silver, lead, and rhenium [4]. - The U.S. Geological Survey is also analyzing the potential inclusion of uranium and metallurgical coal, while arsenic and tellurium are suggested for removal from the list [4]. Group 2: Economic Implications - Inclusion in the critical mineral list can lead to federal funding, simplified permitting processes, and increased competitiveness due to import tariffs [4]. - The proposal aims to reduce U.S. dependence on imported critical minerals and expand domestic production [5]. Group 3: Industry Reactions - The copper industry has been advocating for its inclusion, emphasizing its significance for the economy and national security [5]. - The International Copper Association's president highlighted copper's role in electrification, defense, and clean energy, stating that recognizing its criticality aligns with U.S. interests [5]. Group 4: Market Impact - Following the announcement, stock prices of fertilizer companies listed in the U.S. saw increases, with Mosaic rising by 4.5% and Nutrien by 2.9% [6]. Group 5: Supply Chain Analysis - The U.S. Geological Survey's supply chain disruption model assessed over 1,200 trade disruption scenarios for 84 mineral commodities, estimating potential impacts on 402 industries and the overall economy [7]. - The model indicates that even losing one critical mineral could trigger a chain reaction affecting various sectors, from semiconductors to defense systems, thereby weakening production capacity and job opportunities [8].
