Where are the gold mines mainly distributed in China?

All provinces and cities in China have gold mines except Shanghai. The main ore deposits and producing areas are: Shandong, Henan, Guizhou, Heilongjiang, Shaanxi, Guangxi, Yunnan, Liaoning, Hebei, Xinjiang, Sichuan, Gansu, Inner Mongolia, Qinghai, Anhui and other provinces.

Luoyang, Henan 1

The comprehensive exploration project in Songxian County, Luoyang City, Henan Province includes eight exploration rights: Huaishuping Gold Mine, Dongwan Gold Mine, Qimudigou Gold Mine, Mogou Gold Mine, Shangdaohuigou Lead Mine, Zhanlonggang Lead Mine, Wafang Lead Mine and Lianghekou Molybdenum Mine.

Huaishuping Gold Mine has completed a detailed field investigation, and the estimated resources are over 30 tons, reaching a large scale. The detailed survey of Dongwan Gold Mine has been completed, with a gold resource of 6.3 tons and an average grade of 3.24 g/ton, reaching a medium scale. According to the estimation of the existing engineering control degree, the amount of gold and metal that can be submitted by the two mining areas is nearly 40 tons, and the service life of the mines is expected to be 42 years.

2. Xinjiang

Vein gold in northern Xinjiang, placer gold in southwest and southeast Altai Mountain.

After 20 years of continuous exploration and evaluation, 2 1 gold mineralization zones have been found in the exploration scope of Xinjiang Bureau of Geology and Mineral Resources in Wuqia County, Xinjiang, with an altitude of 3 100 m to 4,300m and an average grade of 2.45g/ton, with a submitted gold resource of 127 ton and a prospective resource reserve of more than 200 tons.

Among them, the width of No.4 mineralization is 85 meters, the length is 4000 meters, the average grade is 2.57 g/ton, the local highest grade is 63.88 g/ton, and the estimated gold resources are 98.33 tons. Now it has become the largest gold mine in Xinjiang.

3. Inner Mongolia

Hadamengou, Inner Mongolia

From September 2065438 to September 2002, the second brigade of the first detachment of the Armed Police Gold Corps discovered a rare single-vein super-large gold mine in China. According to experts' preliminary determination, the gold resource reserve of this vein is nearly 70 tons, with a potential economic value of more than 27 billion yuan.

Urad Middle Banner in Inner Mongolia

It was learned from the Department of Land and Resources of Inner Mongolia Autonomous Region that geological prospectors recently discovered a super-large gold mine in Wulate Zhongqi, Bayannaoer City, with a resource reserve of 148.5 tons and a reserved resource reserve of 130.4 tons, ranking first in the autonomous region.

4. Shandong

Placer gold deposits in the north of northeast China. Placer gold is mainly composed of Heihe River, Huma River, Wulaga River and Huachuan River, which belongs to alluvial placer gold. The United primary gold deposit was discovered in the intrusive body of Mesozoic and Jurassic volcanic rocks. There is a long history of gold-bearing quartz vein mining in Zhaoyuan area, Shandong Province, and there are exquisite gold deposits.

Later, altered granite types were discovered, such as Sanshandao, Jiaojia, Xincheng and other large gold deposits. The reserves and output of gold deposits in this area rank first in China. Yantai discovered 18 gold mining reserve bases, adding 24 1 ton of gold and metal resources. By the end of last year, Yantai had gold resources of 1.80 million tons, and Laizhou alone had more than 600 tons of gold resources.

5. Other regions

Liaoyan gold mining area. Including some gold mines in eastern Jilin and eastern Hebei. Most of them are gold-bearing quartz vein deposits in pre-Sinian gneiss, schist and granodiorite, including Jiapigou, Jinguangyu, Wulong and Zhangjiakou gold deposits.

Gold mining areas in southeastern China. Including vein gold in Hunan and Guangxi, mineralized slate in Banxi system and gold-bearing quartz vein in Bianxi Group. There are many gold mines in this area, but the scale is small. Xiangxi gold mine is the largest gold mine in this area.

Qinling-Qilian gold mining area. This area is characterized by vein groups, high-grade and polymetallic deposits. The representative mines are Qinling, Wenyu, Tongguan and other gold mines.

The terraced placer gold areas of Jinsha River basin in southwest China and some rivers in Sichuan Basin.

Gold mining area in Taiwan Province province. Jinguashi gold deposit is a large gold deposit related to tertiary volcanic rocks.

Gold mining area in Tibet. Distributed in terraces on both sides of the tributary south of the Yarlung Zangbo River.
