What is the "soil" of nearly 700 million tons of rare earth resources for thousands of years?

Science Fiction Network, July 5th (Qin Yingying) According to the Russian satellite news agency quoted the Turkish Daily, a large number of rare earth resources found in Eskiehill, located in northwestern Turkey, can meet the world's demand for 1,000 years. The mining bed found in Eskiehill province contains about 694 million tons of rare earth. After processing, it may bring billions of dollars to Turkey.

Rare earth is the general term for the elements of the 镧 钪 钪 钪 钪 钪 and 钇 钇 钇. There are 250 kinds of rare earth in nature. The earliest discovery of rare earth was Finnish chemist Gadolin. In 1794, he separated the first rare earth "element" (钇 钇, Y2O3) from a heavy ore -shaped ore.

Because there were fewer rare earth minerals found in the 18th century, at that time, only a small amount of oxides that were not soluble in water were used to use chemical legal. In history, this oxide was called "soil", so it was named rare earth.

Rare earth is called "industrial vitamin" and "industrial gold". The rare earth is listed as strategic resources by countries around the world for special uses. Many high -fine weapons, missiles, radar, spacecraft, or equipment must be used. It can also be applied in the metallurgical industry, petrochemical, glass ceramics and agriculture.

The world's rare earth resources are mainly distributed in China, CIS countries, the United States, India, and Australia. Among them, China's rare earth resource reserves account for 24.03%of the world. It is reported that the rare earth ore found in the region includes 10 of the 17 rare earth elements known in the world.
