Brief introduction of China Yindu

"China Yindu" refers to Yongxing County, Chenzhou City, Hunan Province. In 2002, at the annual meeting of China Silver, Yongxing County was named "China Silver Capital" by the Silver Branch of China Nonferrous Metals Association. The output of silver in Yongxing County accounts for 1/4 of the whole country, and gold and silver have been recycled and smelted for more than 300 years. This unique folk traditional process has gradually developed into a traditional industry for extracting precious metals such as gold, silver, lead and bismuth from waste gas, waste residue and waste liquid. The most valuable thing is that there is no silver mine in the county, which is the silver capital without silver mine.
