Muscovite

Muscovite

　　Muscovite refers to a type of mica ore suitable for industrial use and is an important raw material in industries such as electrical manufacturing. The only producing area in Jiangsu Province is Donghai County, Lianyungang City.

More than 130 years ago, farmers in the Qinglong Mountain and Lu Lake areas of Donghai County discovered this mineral. Soon after, a Shanghainese man named Zhang Shouxi and his relatives came to mine here. Between 1940 and 1943, the mineral was heavily exploited by Japanese invaders, resulting in significant losses. From 1957 to 1960, the Northern Jiangsu Geological Team of the Jiangsu Provincial Geological Bureau conducted a survey and evaluation of the Donghai mica deposits. In addition to the two major mining areas of Qinglong and Luchao, over 30 muscovite veins were later discovered in areas such as Chizhuang, Buhou, Shuangdian, and Xiaoguanzhuang. Currently, apart from Vein No. 17 of Qinglong Mountain, which has been exhausted, all other veins remain available for mining.
