At the bottom of the Pacific, a large number of rare earths have been found in China.
According to foreign media reports, scientists have discovered a large number of rare earth resources in the Pacific Ocean. According to a research report released by the American professional magazine Nature Geoscience, the metal mineral is contained in 5000 meters. Under the sea mud.
At present, Japanese researchers have tested 78 possible rare earth resource reserves in the Pacific Ocean and extracted sediment samples from the seabed. Scientists discovered a region of high density of rare earths about 2,000 kilometers from the mid-ocean ridge. It is suspected that only one square of a square kilometer of reserves contains enough rare earth resources to meet one-fifth of the global annual demand.
The test results show that these rare earth resources can be extracted from seabed sludge using acidic substances. Scientists explain that as long as these acids are not dumped in seawater, mining will not pollute the environment. The bigger question should be whether it is technically feasible to extract seabed sludge from the depths of 4,000 to 5,000 meters, and whether such mining is economically cost-effective.
China is the country with the richest rare earth resources in the world. 97% of the rare earth resources in the world rare earth market are from China. In addition to China, some former Soviet countries, the United States and Australia also have certain rare earth resources. Previously, China had imposed strong restrictions on the export of rare earth resources. In 2010 alone, the export volume decreased by 9.3%. If these rare earth resources are developed and utilized in the form of industrial mining, China will lose its monopoly position in this field.
The rare earth element is a combination of 17 chemical elements of the group III subgroup elements é’ª, é’‡ and lanthanides. Rather than the name suggests, rare earth elements are not considered "rare", they are widespread in the earth's crust, but because of their chemical nature, rare earth elements are rarely enriched to the extent that they are economically exploitable.
As an important strategic resource, rare earth is known as “industrial MSG†and can be widely used in building materials, petrochemical, metallurgical machinery and other high-tech fields such as superconducting materials, aerospace and laser. In the production of energy-saving lamps, rare earth energy-saving lamps have become the third generation of new light sources with high light efficiency, high color rendering, energy saving and energy saving, and have been promoted by the state as a key energy-saving product. Rare earth is also an important raw material for LED phosphors, and the current LED phosphor market is dominated by foreign manufacturers.
