Recent Trends in Refractory Gold Treatment Projects in China

Recent events in The Peoples Republic of China indicate that a major effort is underway to increase trade with the western world. Gold production contributes to China's ability to participate in international trade. Consequently, the Chinese government places a high priority on increasing gold production. Many of the operating gold mines in China contain refractory ores that to date have not been efficiently treated. Figure 1 illustrates the description and location of a few of China's major gold mines. China recognizes that the technology necessary to economically treat this ore has been developed in the United States and other western countries. The country has therefore begun to seek assistance in evaluating several potential projects. Organizational structure Gold mining and processing in China is directed by the China National Gold Corp. (CNGC), headquartered in Beijing. The agency has a director in each province who is responsible for exploration, mining and processing. CNGC uses the services of two engineering organizations for metallurgical testing, process development and design engineering for their projects. The largest engineering organization is the Central Engineering and Research Institute for Non-Ferrous Metallurgical Industries (ENFI), also located in Beijing. The second engineering organization is the Changchun Gold Design Institute (CGDI), located in Changchun Jilin province.
