What are the main producing areas of placer gold in China?
The important placer gold (gold) producing areas in China are as follows: \x0d\ 1. Gold mines in Heilongjiang Province: Mohe Gold Mine and Humahe Gold Mine have a long history and are recorded in Qing history. Tuanjiegou Gold Mine was discovered in 1970s, and Laozuoshan Gold Mine was discovered in 1980s, and it has been developed on a large scale. There are more than 400 large and small gold mines in Heilongjiang, including more than 300 placer gold mines and more than 70 gangue gold mines. Gold production has increased steadily. The gold deposits in Heilongjiang Province are mainly distributed in Mohe, Huma, Aihui, Luobei, Huanan, Muling, Dongning and other places, forming a "golden border" from north to south, with an accumulation area of 500-2,000 square kilometers in general and up to 6,000 square kilometers at most. \x0d\2。 Gold Mine in Jilin Province: Jiapigou Gold Mine in Hua Xun County, Jilin Province has a long history.

Important large-scale gold deposits are Wulong, Sidaogou and Jinchanggouliang, while small and medium-sized gold deposits are Beipiao, Erdaogou, Koubangou Mao Jiazhuang and Nailingou. \x0d\ Gold Mine in Hebei Province: The mining history of this province can be traced back to the Sui and Tang Dynasties, and the amount of gold mining in Hebei Province in the Ming and Qing Dynasties was quite large. The gold mines in the province are mainly located in Chengde, Tangshan and Zhangjiakou. There are more than 530 gold mines distributed in 32 facilities in 7 regions. It is characterized by dispersion and small scale. \x0d\4。 Gold mines in Shandong Province: Gold mining in this province can be traced back to at least the Northern Song Dynasty. Now it has become one of the important gold production bases in China. The gross output value, output, profit, foreign exchange and gold reserve of gold rank first in China. Four large and medium-sized mines, Jiaojia, Xincheng, Yinan and Rushan, newly built and rebuilt by the state, show a good prospect for gold production in Shandong Province. At present, Shandong Province accounts for five of the national 10 key gold mines, of which Zhaoyuan Gold Mine and Sanshandao Gold Mine are well-known at home and abroad. In recent years, the mass gold mining industry in Shandong Province has also developed rapidly, with more than 250 gold mining sites in Yantai and Linyi. Gold in Shandong Province is mainly concentrated in Zhaoyuan-Yexian area of Jiaodong Peninsula, with relatively concentrated producing areas and easy to be mined on a large scale. \x0d\5。 Gold mines in Shanxi Province: The gold mines in this province can be traced back to at least the Yuan Dynasty. From 65438 to 1930s, there were about 20,000 gold prospectors in Zhangsigou, Daixian County, Shanxi Province.

There is also a large placer gold mine in Hengkou Basin with stable grade, shallow burial and easy mining. At the same time, two medium-sized placer gold mines were found at both ends of Hengkousha Gold Mine. Hanzhong basin is simply a cornucopia. At present, a large-scale gold deposit has been discovered in Yangpingguan, Hanzhong, with high and stable ore body grade, which has good economic value and mining value. \x0d\7。 Gold mines in Hunan Province: The gold mines in Hunan Province are earlier than those in other provinces, and have been recorded in the Eastern Zhou Dynasty. The ancient gold ore field is located on the Yanshui River in the west of Hengyang, stretching for dozens of kilometers. There are more than 65,438+0,000 ancient gold mining wells in Hongluo Temple and Longgutang. After more than 2000 years of mining, the shallow and high-grade gold mines in Hunan have been basically mined, but the underground gold resources are still very rich. There are dozens of associated gold mines in the province, which are suitable for comprehensive mining. Gold-bearing quartz veins are concentrated in three tectonic uplift areas: central Hunan, eastern Hunan and western Hunan. \x0d\8。 In addition to the above-mentioned producing areas, Sichuan, Zhejiang, Xinjiang, Qinghai, Inner Mongolia, Guangxi, Henan and Taiwan Province provinces also have considerable gold production.
