Changchun Gold Research Institute was founded in 1958, which is the only national level scientific research organization specialized in the research of basic theory on gold industry and engineering technology development. At the same time, the Technology Center of China National Gold Group Corporation, National Monitoring Inspection Center for Gold, Silver and Their Products, and China Gold Environment Monitoring Center are affiliated with Changchun Gold Research Institute; “Gold Magazine” is also set up in this institute.
