A Metallurgical Exploration Institute of China Metallurgical Metallurgical Exploration in the Great Wall of Jidong Manganese stratigraphic breakthrough. High-quality manganese ore is a national shortage of minerals, from the distribution of resources in our country, most of the high-quality manganese ore concentrate in the south, especially around the Yangtze Platform, the northern mineralization conditions are inherently inadequate, has been the geological concern of the Great Wall of Jidong manganese- Prospecting, in addition to the discovery of the eastern section of Wafangdian large manganese ore, found in the western ditch silver manganese ore
