Sulfur

Basic Introduction to Jian Zhan Jian zhan, or tea cups, originate from Jianyang District, Nanping City, Fujian Province. Nanping City has identified 11 large-scale mineral deposits, such as piezoelectric quartz and melting quartz in Zhenghe County, sulfur mines in Pucheng County, fluorite mines in Shaowu, Jianyang, Songxi, and Guangze Counties, graphite mines in Jianyang, niobium-tantalum mines in Yanping, limestone and cement siliceous raw materials in Shunchang. There are 15 medium-sized deposits, including four lead-zinc mines, four fluorite mines, one limestone mine, two serpentine rock mines, two sulfur mines, one niobium-tantalum mine, and one cement siliceous raw material deposit. Over 80 small-scale mineral deposits have been identified. More than 700 known mineralization points and over 200 geochemical anomalies have also been recorded, along with over 200 heavy mineral anomalies (including 14 gold anomalies and 112 tungsten, tin, and molybdenum anomalies), over 50 diversion anomalies, and over 20 magnetic anomalies. These conditions make the area suitable for producing jian zhan. Jian zhan typically have wide mouths and small bases, some resembling funnels. They often have ring feet that are shallow, with a characteristic knife-cutting technique (commonly known as chamfering) at the foot base, and the bottom of the foot is slightly outwardly…
