Museum Quality Mineral Specimens, Daye Copper Mine

Ancient Chinese Dynasties: Unveiling the Mystery of Sources of Copper


When the Bianzhong of Marquis Yi of Zeng (Zenghouyi) unearthed in 1978 in the Zenghouyi Tomb in Sui Co., Hubei Province, China, the world was shocked. The discovery totally changed our understanding of prehistoric human, who were able to create such a beautiful set of musical instruments. The Bianzhong was built around 2,451 years ago (433 BC) and is the most extensive, heaviest (10.5 tons!) and best preserved orchestral instrument known-to-date. We’re all amazed and can’t help thinking – where did such a huge amount of raw copper materials come from? The answer is – The Tonglushan Mine (Daye Copper Mine).

Daye Copper Mine – The Oldest Mine In History Still In Operation


Tonglushan Mine (Daye Copper Mine), Hubei, China


The Daye County in Hubei Province has long been an important site of metal production due to its mineral richness in high grade copper and iron, but also in other minerals. Located in the eastern part of Hubei Province, the Daye Copper Mine on the south bank of the Yangtze River is known as the "Golden Land of Baili, Cornucopia in the South of the Yangtze River". Radiocarbon dates indicates that the area has been mined since the first recorded dynasty in China, the Xia Dynasty (2070-1600 BC) and has a history of more than 2,400 years. The Tonglushan ancient mine was rediscovered in 1965 and excavated between 1973-1985, during which 8 large mining sites, 50 smelting sections, 12 smelting furnaces, 231 vertical mining shafts, more than 100 horizontal inclinded tunnels and thousands of mining tools were revealed. It is estimated that the smelted blister copper reached 80,000 to 120,000 tons.

You may wonder which mine(s) should officially be called The Daye Copper Mine, be it the Tonglushan Mine, the Fengjishan Mine and the Tieshan Mine. The answer is, they are all called The Daye Copper Mine because they are mountains and underground ore deposits interlinked to form the whole Daye Copper Mine area, see the diagram below:



Mining Technology in Ancient China


There was a gradual evolution in the complexity of mining operations in ancient China of which shaft sinking was initially adopted to excavate a vertical tunnel from the top down during 1100-800 BC. Whereas later the extraction was also followed by underground tunnels (800-500 BC) and from 500 BC onwards, a sophisticated and complex process of extraction was developed whereby the ore was extracted in stair-crosscut galleries and tunnels.

How is copper found?


Believe it or not, it’s by flowers! Elsholtzia and Commelina communis (commonly known as the Asiatic dayflower) are the dominant species that vastly grow over the copper mining spoil heaps and copper-contaminated soil of the areas along the Yangtze River. Chemical analytical data show that these plants can accumulate copper to various extents, depending on the copper content of the supporting soils and plant species. Therefore, these flowers can serve as pioneer species for reclamation of copper mined land and that was exactly how people discovered the Tonglushan Ancient Mine.
