On the afternoon of the 29th, it was learned from the Provincial Bureau of Geological Survey that the first geological team of Zhejiang Province discovered a super-large antimony polymetallic deposit in the northwest of Zhejiang Province, and initially discovered that the antimony resources exceeded 70 tons, worth about 70 billion yuan.
It is reported that rare earths include 17 kinds of metal elements such as lanthanum, among which lanthanum is mainly used in cutting-edge technology fields such as defense, military industry, aerospace, nuclear energy and superconductors, and belongs to the national strategic reserve of rare earth metals. According to Yang Xiaochun, the chief engineer of the first geological brigade of the province, the market price of base metals is generally 4 times that of gold, and it has been as much as 10 times in history.
The proven large-scale antimony polymetallic deposits are accompanied by a large-scale polymetallic ore mainly composed of silver, including 800 tons of silver, 130,000 tons of lead and zinc, and 3,000 tons of a large-scale cadmium deposit. Tin 7000 tons, 镓400 tons, 铼5.5 tons, all reached the medium scale. In addition to the first discovery of super-large niobium deposits in Zhejiang Province, it is also the first time that such a large number of noble metals, non-ferrous metals and rare metals have been found in the same mine.
These rare metals are also worth a fortune. It is understood that the market price of tin is one ton of 200,000 yuan; the price of lutetium is about the same as that of silver, about one ton of six million yuan; and one ton of sixty million yuan is equivalent to ten times that of silver.
Over the years, many domestic geological experts believe that under the special geological conditions of volcanic rocks in Zhejiang, non-metallic minerals are mainly formed in the volcanic-covered areas on the surface, and the metamorphic rocks under the volcanic rocks have favorable conditions for generating metal deposits. Some important Minerals have good metallogenic geological conditions and large prospecting potential in Zhejiang Province. However, in the past, due to theories, equipment, and practical understanding, geological prospecting mainly stayed on the surface and shallow areas. In addition to frequent discovery of non-metallic mineral resources such as fluorite and pyrophyllite, few other mineral resources were discovered.
“This discovery can be described as a milestone in the history of geological exploration in Zhejiang Province.†Yang Xiaochun said that in 2006, the first Geological Exploration Bureau of the Provincial Geological Survey Bureau had the right to explore the land. Later, it found here that the old people used to mine silver mines. Ancient pit, silver slag and other relics. However, until last year, the mine was still dominated by mining silver mines.
The discovery of embarrassment was due to the enlightenment of a visit to Yunnan. In the second half of last year, the leader of the First Geological Exploration Bureau of the Provincial Geological Survey Bureau, Xu Gang and Yang Xiaochun, all went to Mengzi County, Yunnan Province to inspect a lead-zinc mine and learned that there is indium such as indium. “Zhejiang was thinking at the time that there were no rare elements in the mines in Zhejiang.†After the inspection came back, they sampled and tested the mine. As a result, they discovered that there are many kinds of rare elements. Among them, the highest content of antimony is available. Refined 14 grams.
"Zhejiang is not without mine, but did not find it!" Industry sources said that the successful discovery of antimony ore has accumulated valuable experience in the search for similar ore. Among the 19 important metallogenic belts identified by the country, the “Chinhang metallogenic belt†and the “Wuyishan metallogenic belt†pass through Zhejiang Province, and the covered area covers more than half of the total geographical area of ​​Zhejiang.
Zhejiang prospecting has great potential. In the past five years, Zhejiang Province has identified more than 50 mineral sites for further exploration or development, including two large-scale metal mines such as uranium and silver polymetallic ores and ten or more medium-sized metal ores such as copper, lead, zinc and molybdenum. Above, there are more than 10 large-scale non-metallic minerals such as fluorite and pyrophyllite. The Provincial Bureau of Geological Exploration stated that it is confident to find more and better mines and provide strong mineral resource support for Zhejiang's economic and social development.
