中国将加强找矿行动陆海统筹，统筹深海资源调查

Core Insights - The article discusses the increasing global demand for critical metals such as nickel, cobalt, and copper, leading to a strategic focus on deep-sea mining as a new frontier for resource exploration and technological competition among nations [2][4]. Group 1: Deep-Sea Mining Overview - Deep-sea mining involves both the exploration and development of resources on a nation's continental shelf and in international seabed areas regulated by the International Seabed Authority [3]. - The primary types of deep-sea metal deposits include polymetallic nodules, cobalt-rich crusts, metal sulfides, and deep-sea rare earths, which are essential for various industries, particularly the renewable energy sector [4]. Group 2: Strategic Importance - China's high dependency on foreign sources for certain metals, such as cobalt (99% dependency) and copper (77% dependency), underscores the importance of deep-sea mining for ensuring a stable supply chain for strategic resources [4]. - The economic value of deep-sea mining is significant, with the potential value of extracted materials from seabed nodules estimated to be between 6,000 to 7,000 yuan per ton, compared to much lower values for land-based mining [4]. Group 3: Technological and Environmental Challenges - The challenges of deep-sea mining include technological difficulties, environmental concerns, and high operational costs, with a focus on achieving reliable, unmanned operations in extreme underwater conditions [6][8]. - Recent advancements in deep-sea mining technology, such as the "Kai Tuo No. 2" mining vehicle, demonstrate China's progress in this field, achieving significant milestones in deep-sea operations [8]. Group 4: Future Development and Collaboration - The Chinese government has outlined a long-term roadmap for deep-sea mining, emphasizing the need for coordinated efforts in resource exploration and environmental protection [10]. - Future development should focus on building a sustainable framework for deep-sea mining, enhancing global cooperation, and establishing responsible supply chain standards [10][12].
