中国发现“无价之宝”，每吨估价46亿，日本破防：怎么又是中国的

Core Viewpoint - China has made significant discoveries in rare metal resources, particularly in rubidium and rhenium, enhancing its position in the global market and reducing reliance on imports [1][17]. Group 1: Rubidium Discovery - China has discovered a super-large independent rubidium mine with a reserve of 175,000 tons, which is unprecedented globally [1][4]. - Rubidium is crucial in high-tech, medical, and renewable energy sectors, previously difficult to extract and costly [3][6]. - The global demand for rubidium is increasing, with annual production only around 4-5 tons, leading to a significant supply gap [8]. Group 2: Global Market Impact - With the new rubidium mine, China can potentially meet global demand for over a thousand years, shifting from a passive to an active role in the market [8][9]. - The estimated value of rubidium is around 4.6 billion per ton, reflecting its scarcity and importance in high-tech applications [8][9]. - Japan, heavily reliant on imported rubidium, faces increased pressure and potential supply chain instability due to China's resource advantage [9][11]. Group 3: Rhenium Discovery - China has also discovered rhenium, a rarer metal than rubidium, with a reserve of 176 tons, ranking fourth globally [13][14]. - Rhenium is essential for aerospace applications, particularly in turbine blades, enhancing performance and longevity [13][14]. - China has developed its own extraction and application technologies for rhenium, breaking the previous technological monopoly held by developed countries [14][15]. Group 4: Sustainable Development - The development of both rubidium and rhenium resources emphasizes efficiency, technology, and environmental protection [15][16]. - China is implementing strict emission monitoring during the extraction processes to ensure sustainable development [16]. - The focus on self-sufficiency in these rare metals supports the growth of high-tech, renewable energy, and aerospace industries [17][18].
