(Tokyo News) Japan plans to extract the materials required to manufacture electric vehicles and hybrid vehicles from the Underwater Island near the Pacific Nanda Island in 2024 to reduce dependence on China's rare earth.
Nikkei reports that Japan has already found mud with rich soil metals in the 6000-meter-deep sea bed in Minami-Ortishima Island.Nan Bird Island is a coral reef, which is located about 1900 kilometers southeast of Toast.
To extract these rare earths, Japan must first develop technologies to extract resources from a depth of 5,000 to 6000 meters.
Since this sea area is located on the typhoon path, the black tide (Kuroshi, also known as the warm current of Japan) is also one of the fastest foreign flow in world.Face great technical obstacles.
When mining oil and natural gas from the bottom of the sea, once a hole is drilled on the surface, the sediment will erupt under strong pressure.The underwater silt containing rare earth metal does not have this advantage, and the resources must be led to the surface by pumping and other methods.
Japan will start development required for development next year.The Japanese Parliament recently approved at a special meeting that 6 billion yen (about S $ 61.0 million) in the second supplementary budget of fiscal 2022 was used to develop and manufacture pipelines up to 6,000 meters in order to conduct experimental miningEssence
The research on the mining resources of Nanta Island is underway.From August to September this year, the researchers successfully extracted the sediment from the 2470 -meter -deep sea bed.
At present, almost all rare metals in Japan are dependent on imports, 60%of which are from China.The rare earth resources imported from China include the necessary materials (Neodymium) for wind power, and the Dysprosium for making electric vehicles.
