China's seven major mineral capitals include gold, nickel, tungsten, tin, etc.
The prosperity of a country, in addition to the strong economy, culture, and technology, the local geographical environment, mineral resources, etc. are also important components. Looking at many countries in the world, due to the rich resources of oil, coal, gold and other rare resources, these comprehensive strengths Countries that are not strong are very rich.
China is a large developing country with a vast territory and abundant resources, rich in resources, and many mineral resources have advantages in the world. For example, among the proven rare earth reserves, my country ranks first in the world, accounting for about 43% of the world's total reserves. Therefore, China provides 88% of the rare earth needed by the world.
As China has strengthened its management of rare mineral resources, and should not allow precious minerals to repeat the price of cabbage, the state has strictly protected such strategic mineral resources. In particular, long-term plans are made for important minerals such as antimony, tungsten, zinc, and molybdenum used in manufacturing and high-tech fields. Those areas such as the capital of gold mines, the capital of tungsten mines, the capital of zinc mines, and the capital of nickel mines have made important contributions to China's economic development.
Zhaoyuan City is located in the economically developed Yantai, Weihai, and Qingdao metropolitan areas in Shandong. It is a place full of dreams and rich in gold. Zhaoyuan is famous for its gold production in China, and it is known as the "Golden Capital of China". There are three things in Zhaoyuan that are well-known throughout the country. The first is gold, the second is fans, and the third is Red Fuji apples. As the golden capital of China, Zhaoyuan is the largest gold-producing city in China, accounting for one-eighth of the country’s proven reserves. As early as 2002, it was named China’s Golden Capital by the China Gold Association.
Gejiu City is a metallurgical industrial city that mainly produces tin, and produces lead, zinc, copper and other non-ferrous metals. It has a history of mining tin ore for about 2000 years. It is famous for its rich reserves, advanced smelting technology and high purity of refined tin at home and abroad. It is the largest modern tin production and processing base in the country and the earliest tin production base in the world. It is a well-known "Xidu" at home and abroad.
After the founding of New China, Gejiu produced a total of 1.92 million tons of non-ferrous metals, including 920,000 tons of tin, which accounted for more than 70% of the national tin output. Tin is mainly used in the metallurgical industry to produce tin plate and various alloys. Tin plate is the main consumption area of tin, accounting for about 40% of the consumption of tin. It can be used as a container for food and beverages and widely used in wood preservatives and pesticides.
Dayu County, Jiangxi Province, is named because it is located at the northern foot of Dayu Mountains. It is rich in tungsten resources and is the largest tungsten ore base in my country. The mountains in the territory are affected by the Yanshanian geological tectonic movement and formed a world-renowned tungsten deposit. The world-famous "World Tungsten Capital". The mineralized area in the territory is about 30 square kilometers, and there are more than 3,000 large and small veins. There are many types of minerals in the deposit, including 48 kinds of minerals. The main metal minerals are wolframite.
Tungsten ore is widely used in the fields of electrical appliances, petroleum, electronics, chemical industry and military industry, and has shown its important role in the field of cutting-edge technology. my country is the country with the largest reserves and output of tungsten ore, and is known as the "kingdom of tungsten production". China is the country with the richest tungsten ore resources in the world. As of the end of 2016, my country's tungsten ore reserves were 10.16 million tons.
Luanchuan County, named after the phoenix-like Luan bird in ancient times, is known as the "Luoyang Back Garden". It is also a key satellite city planned and constructed by Luoyang City. China is rich in molybdenum resources. By the end of 1999, China's total reserves of molybdenum metal were 8.336 million tons, ranking second in the world. Molybdenum resources in Henan Province are the most abundant, with molybdenum reserves accounting for 30.1% of the country's total reserves.
Pure molybdenum wire is used in high temperature electric furnace, EDM and wire cutting. The molybdenum sheet is used to manufacture radio equipment and X-ray equipment; it is mainly used in the manufacture of artillery chambers, rocket nozzles, and tungsten wire supports for light bulbs. The addition of molybdenum to alloy steel can improve the elastic limit, corrosion resistance and maintain permanent magnetism.
Lanping is the only Bai Pumi Autonomous County in China. It is located in the core area of the "Three Parallel Rivers" World Natural Heritage of Nu, Lancang and Jinsha Rivers in the southwest of China. Naturally, it has become the central station of the tourist passage in the Three Parallel Rivers area. Lanping County is rich in biological resources. It has the largest lead-zinc mine in Asia and the second largest in the world. It has a proven reserve of 14.29 million tons and a potential value of more than 200 billion yuan. Therefore, Lanping is known as the "Green Zinc City".
Lanping’s mineral resources are unique, and it has long been famous at home and abroad. Zinc has good calenderability, corrosion resistance and wear resistance. It is the third important non-ferrous metal among the 10 commonly used non-ferrous metals. It is widely used in metallurgy, building materials, light industry, electromechanical, automobile, military industry, coal, petroleum, etc. industry.
Jinchang Nickel Mine is located in the north of Yongchang County in the Hexi Corridor. It is a rare nickel mine in the world. It is rich in nickel sulfide, gold, silver and platinum group metals. After the Jinchang Nickel Mine was put into operation in the 1960s, my country's history of not producing nickel has ended, making my country one of the countries with the largest nickel resources in the world.
Jinchang Nickel Mine can directly extract more than ten kinds of products from the ore, among which the output of nickel and platinum group metals accounts for 85% and more than 90% of the country's total. Jinchang has become my country's largest nickel production base, copper, cobalt, gold, silver and platinum group metal refining center, and is known as "China's Nickel Capital".
At the end of the Ming Dynasty, the world's largest antimony resource was discovered in Lengshuijiang, Hunan. With the rise of the machinery manufacturing industry, the use and demand for antimony expanded, and Hunan's antimony industry ranked first in the country. In the decades since 1908, China's antimony production often accounted for more than 50% of the world's total output. Only the tin mines produced 36.6% of the world's output from 1912 to 1935 and 60.9% of the country's total.
Antimony is a silver-gray metal. It is an acid-resistant substance at room temperature and a poor conductor of electricity and heat. It is not easy to oxidize at room temperature and has corrosion resistance. Antimony and antimony compounds were first used in wear-resistant alloys, printing type alloys and the munitions industry. With the development of science and technology, it has now been widely used in the production of various flame retardants, enamel, glass, rubber, pigments, ceramics, plastics, semiconductor components, medicine and other industries.
