Why is Baiyun Obo full of temptation?

Baiyun Obo, which means "fertile holy mountain" in Mongolian, is located in Baiyun mining area, about 0/50 km north of Baotou City. It is a super-large deposit composed of iron, niobium and rare earth, and its rare earth and niobium ores are world-famous. In addition, it is also found that there are more than 7 1 elements and 170 minerals in Baiyunebo, which is also a cornucopia of new minerals. The whole mine is divided into three ore bodies: main mine, east mine and west mine, with a length of about 16 km from east to west and a width of 2 ~ 3 km from north to south. Mineral resources are rich and diverse, with huge reserves. Rare earth resources are unique, accounting for 97.7% of the country's total reserves and more than 80% of the world's total reserves. Therefore, it is known as the "hometown of rare earths in the world" and has won the reputation of "rare earth capital" for Baotou City. The construction of the mining area is changing with each passing day, and it is known as a bright pearl on the Saibei grassland. It has become an important economic, cultural, transportation and commercial activity area outside the Great Wall, and it is a tourist attraction of "mine scenery tour" and "rare earth industry tour" that Chinese and foreign tourists compete to reach. Baiyunebo mine was first discovered by China geologist Ding Daoheng. 1July, 927, Ding Daoheng went to the northwest with the Sino-Swiss scientific investigation team, and took the grassland of Wulanchabu League to find the main mine of Baiyunebo. 1935, another geologist in China, He, made a detailed indoor study of the ore samples brought back by Ding Daoheng, and made another major breakthrough. He discovered two kinds of rare earth minerals, named "Baiyun Mine" and "Obo Mine". At that time, Professor Yan Jici determined the contents of rare earth elements such as lanthanum, cerium, praseodymium and neodymium in minerals. This precious discovery laid the foundation for the further development of Baiyun Obo. 1950, the then Central People's Government organized a geological team from Baiyun Obo and began large-scale geological exploration in this area. Baiyun ebo is known as a pearl on the grassland.
