The Gejiu Tin Mine Smelting Site (个旧锡矿山冶炼遗址) is located at Chongzipipo (冲子皮坡), Gejiu City (个旧市), Yunnan Province. It dates back to the Eastern Han Dynasty and covers an area of about 200 square meters. Archaeological discoveries include tin ingots, silver ornaments, Han Wuzhu coins, and large amounts of copper and tin slag, providing valuable evidence for the study of ancient Chinese smelting technology and mining development.
- Chinese Name: 个旧锡矿山冶炼遗址
- Location: Chongzipipo (冲子皮坡), Gejiu City (个旧市), Yunnan Province
- Period: Eastern Han Dynasty
- Site Area: about 200 square meters
Site Discovery
Archaeologists uncovered a large number of smelting relics at the site, including tin ingots, silver ornaments, Han Wuzhu coins, and abundant copper and tin slag. These findings suggest that during the Eastern Han period, the site already had relatively advanced smelting technology and operated on a considerable scale.
Smelting Furnace Structure
One of the smelting furnaces at the site is relatively well-preserved, measuring 5.20 meters in length, 2.30 meters in width, and 0.97 meters in remaining height. The furnace walls are covered with thick slag, mainly composed of lead and tin. Analysis of the slag indicates that the smelting technology of the time was capable of effectively separating metals such as tin and lead.
Historical Records
The Geographical Records in the Book of Han (汉书·地理志) notes:
“Bengu (贲古, present-day Mengzi 蒙自 and Gejiu 个旧) to the north produced tin; Xiyang Mountain (西羊山) produced silver and lead; Nanwu Mountain (南乌山) produced tin.”
This shows that the Gejiu region was already an important source of mineral resources during the Han Dynasty, particularly rich in tin. Gejiu Tin Mine is one of the largest tin mines in China, with reserves and output of national and even global significance.
Archaeological Value
The discovery of the Gejiu Tin Mine Smelting Site (个旧锡矿山冶炼遗址) holds great importance for the study of ancient Chinese mining development, smelting technology, and economic history. It demonstrates the advanced smelting skills of the Eastern Han period and reflects the importance of mineral resources in society at the time. The discovery of Han Wuzhu coins also provides insights into the currency circulation and economic activities of the period.
Protection and Research
The Gejiu Tin Mine Smelting Site (个旧锡矿山冶炼遗址) has been designated as an important cultural relic protection unit. Authorities have implemented measures for its preservation and research. Continued archaeological excavation and study are expected to reveal further information about ancient smelting technology and mining development.
