中国将加强找矿行动陆海统筹，统筹深海资源调查——找矿走向深蓝

Core Viewpoint - The deep sea is rich in polymetallic nodules containing critical metals such as manganese, copper, cobalt, and nickel, which are essential for various industries, particularly the new energy sector [1][4]. Group 1: Demand and Strategic Importance - The global demand for key metals like nickel, cobalt, and copper is surging, making deep-sea mining a new frontier for technological and strategic competition among nations [2]. - China's reliance on foreign sources for certain metals is high, with cobalt dependency reaching nearly 99% and copper at 77%, highlighting the strategic necessity of deep-sea mining for resource security [4]. Group 2: Economic Value and Technological Advancements - The economic potential of deep-sea mining is significant, with the value of metals extracted 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]. - Advancements in deep-sea mining technology, such as the "Kaituo No. 2" mining vehicle, have achieved breakthroughs, including a successful sea trial at depths of 4,000 meters, indicating progress in China's deep-sea mining capabilities [7]. Group 3: Challenges in Deep-Sea Mining - The primary challenges in deep-sea mining include technological difficulties, environmental concerns, and high operational costs, with the need for reliable, autonomous operations in extreme underwater conditions [6][8]. - Environmental risks are significant due to limited understanding of deep-sea ecosystems, which may be adversely affected by mining activities [7]. Group 4: Future Development and Strategic Planning - China has outlined a long-term roadmap for deep-sea mining, emphasizing the need for coordinated resource exploration and sustainable practices [9]. - The focus for future development should be on enhancing global cooperation, reducing uncertainties, and establishing responsible supply chain standards for deep-sea minerals [10][11].
