Introduction
Yunnan copper mine is located in Yunnan province in China and is one of the most abundant copper resources in the world. It has been mined for more than 3,000 years, and has been a major source of copper and other metals for ancient civilizations in Asia. This copper mining district is unique in China, the scale is great, the reserves are abundant and the mining process is simple and convenient.
History
Yunnan copper mine has a long history, with records of mining activities dating back to the Warring States period (5th century BC). It is said that the Chinese then used the copper to fabricate bronze statuettes of emperors and warriors. During the Ming and Qing dynasties, copper smelting workshops and mines appeared in different parts of the province, and the copper output gradually increased. The most important of these mines were located in Jianchuan, Fengqing, Yuxi and Tonghai counties.
Minerals
The Yunnan copper mine is rich in minerals, including copper ore, tin ore, zinc ore, lead ore, and other metal ores. Aside from copper, the mine also yields tin, zinc and lead. The mineral ores have been subjected to various tests and their metal content has been authenticated.
Current Workings and Extraction
Currently, Yunnan copper mine is operated by Yunnan Copper Industry Co. Ltd, which is the largest and most modernized copper mining entity in China. The company has invested greatly in modern technologies to improve the safety and efficiency of the mining process. Various development methods are employed and large scale open-pit and underground mining is done through the use of explosives, explosives and machinery.
