Is there a mine in Hongda?

No. hongda shares: the company does not have its own mines, and all zinc concentrates needed for smelting are purchased from abroad. Sichuan Hongda Co., Ltd. was established in 1979, restructured into a joint-stock enterprise in 1994, and successfully listed on the Shanghai Stock Exchange in 200 1 (stock code: 60033 1). Now it has developed into a listed company integrating metallurgy and chemical industry.
