Xiaoshiqiao Yi Township was originally a humble mountain township in Hongta District, Yuxi, Yunnan. After July 10, here will affect the world.
4 kilometers northeast of the township government, a mountain of red soil clay with corn and potatoes is marked as ZK4300-this is an exploration borehole number. It is this number that makes this red soil no longer ordinary.
Scientific demonstration surveys and predictions indicate that from here to the 3,800 square kilometers of land in central Yunnan, lithium oxide resources are as high as 4.89 million tons. This also means that here will form a world-class lithium resource base.
"Yunnan Province is promoting lithium resource development at a high level, and has formed a research and development consortium to increase the exploration and research of new lithium resource base demonstration areas and accelerate the process of industrialization." said Zhao Haibo, deputy director of the Yunnan Provincial Department of Science and Technology.
Innovative prospecting theory, world-class lithium mineral resources have broad prospects
At 3 pm on the 10th, with the opening order issued, the light drilling rig was started, and within 10 minutes, two workers got the first core at about 60 cm from the surface of the ZK4300 borehole.
"We laid holes to expose the situation of ore-bearing geological bodies. The geological continuity here is very good. The width of the exposed areas of ore-bearing bodies on the surface varies from 20 to 50 meters, and the prospecting depth is from 0 to 500 meters." Wang Changbing, an engineer of the 2009 Geological Brigade of Yunnan Nuclear Industry, told Sci-Tech Daily.
Rare metal lithium is an important strategic resource, widely used in emerging fields such as batteries, medicine, nuclear industry, aerospace, new energy vehicles, etc. It is an indispensable raw material for modern high-tech industries and is known as "21st century new energy "Metals" and "metals that promote world progress" have high economic and strategic value.
Wen Hanjie researcher team of Institute of Geochemistry, Chinese Academy of Sciences has long been engaged in the research of lithium mineralization theory and prospecting technology. Three years ago, the project team discovered the extraordinary enrichment of the strategic key metal lithium-gallium-rare earth in the Carboniferous and Permian clay rocks in Guizhou, Yunnan and other places, especially lithium extraordinary enrichment is the most noticeable .
On the basis of in-depth research, they took the lead in proposing a new type of mineral deposit and a new metallogenic model of "carbonate clay type lithium deposit", and obtained a total of about 7.2 square kilometers in the Guanyinshan and Yuxi Xiaoshiqiao blocks of Kunming. The amount of 344,600 tons of lithium oxide resources reached a very large scale. Based on the speculation of the Xiaoshiqiao target area, it is predicted that the lithium oxide resource in central Yunnan is about 4.89 million tons.
Academicians Wu Fuyuan and Xu Yigang of the Chinese Academy of Sciences visited the site and gave high evaluations; Academician Zhai Mingguo of the Chinese Academy of Sciences and Mao Jingwen of the Chinese Academy of Engineering also gave high evaluations at the project consultation meeting.
My country has a huge scale of such rock formations, so carbonate clay-type lithium resources have broad resource prospects.
The strategic position of lithium resources is prominent, and the 100 billion-level pillar industry is coming
"According to the data obtained from previous scientific research and exploration, the average grade of lithium deposits in central Yunnan is about 0.3% and the highest is 1.02%. According to the relevant evaluation standards, the average grade of 0.2% is economically valuable." Li Shihua, director of Yuxi Science and Technology Bureau, told Science and Technology Daily Reporter, because lithium resources in central Yunnan are enriched between montmorillonite layers, the ore layer is shallowly buried, and some are directly on the surface. The mining conditions are better, and even open pit mining is possible.
The development of new energy has become an important way to ensure the security of my country's energy supply and adjust and optimize the energy structure. The excavation of lithium deposits in central Yunnan will greatly change the pattern of lithium resources in the world.
"As a strategic resource and an emerging industry, lithium resource development and follow-up industrial chain development are in line with Yunnan Province's deployment to build a world-class'green energy brand', and it is expected to develop into a pillar industry of 100 billion in the future." Zhao Haibo said that lithium resource development and The follow-up industrial chain development involves a wide range of areas, and requires the coordination and coordination of the government, enterprises, universities, and scientific research institutions, and concerted efforts.
"The research, exploration and development of the new lithium mine resources in Xiaoshiqiao is a major opportunity for the economic and social development of Yuxi City." Xie Shiqing, a first-level inspector of Yuxi City Government, told reporters that in the next step, they will cooperate with the exploration work and do their best This large article on the development and utilization of new lithium resources.
This time, Yunnan Nuclear Industry 2009 Geological Brigade adopted a green portable full hydraulic drilling rig, minimally invasive prospecting, less land occupation, it can be achieved without cutting a tree or occupying a piece of agricultural land.
"We will conscientiously do a good job of avoiding ecological protection red lines, basic farmland, water source protection areas, forestry protection areas and surrounding environmental protection measures, and conduct scientific research and investigation in accordance with laws and regulations." As a representative of the industrial development platform, Chairman of Yunnan Ronghe Investment Holding Company Liu Runxuan said that they will coordinate the strength and resources of all parties, and work together with the Kunming Branch of the Chinese Academy of Sciences and other partners to jointly complete the content of the mission statement of the scientific research and preliminary research project.
