日本深海稀土开采引热议，中方淡定回应显实力

Group 1 - Japan has announced the successful extraction of rare earth-containing sediment from the seabed near Minami-Torishima, which is seen as a significant step towards reducing dependence on specific countries and enhancing economic security [2][4] - The rare earth deposit is located 1,800 kilometers southeast of Tokyo and is claimed to have a high reserve of 16 million tons, potentially meeting global demand for hundreds of years, primarily consisting of heavy rare earths [6][8] - The extraction process faces significant challenges due to the depth of 6,000 meters, where equipment must withstand 550 times atmospheric pressure, making operations difficult and increasing the likelihood of equipment failure [8][10] Group 2 - The estimated cost of extracting one kilogram of rare earth ore ranges from 8,000 to 15,000 Japanese yen, approximately 400 RMB, which is higher than the cost of purchasing refined rare earths [10][11] - Japan's rare earth purification technology is relatively advanced, but it still lags behind China's capabilities, which can achieve purities of up to 6N compared to Japan's 4N [11][13] - The cost advantage of Chinese rare earth production is significant, with estimates showing that Chinese companies can produce at 3 to 4 USD per kilogram, while competitors like Lynas face costs of 10 to 15 USD per kilogram [13][14] Group 3 - China's dominance in the rare earth industry is attributed to its ability to produce high-purity, low-cost, and low-pollution rare earths, making it difficult for other countries to compete unless there are significant changes in the industry [16] - The current geopolitical landscape suggests that Japan's ambitions in the rare earth sector may not be realized during the tenure of its current leadership, especially given China's control over the rare earth supply chain [16]
