Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.
Wubu County is located in the southeastern corner of Yulin City, in the north of Shaanxi Province, China, and on the western bank of the Yellow River. It is opposite to Shanxi's Liulin County and also borders Jia County and Suide County.

The Hushan or Tiger Mountain Great Wall, known to Koreans as Bakjak Fortress, is considered by Chinese academia to be the most easterly known part of the Great Wall of China. About 600 metres of remains were excavated here in 1989. In 1992, a section of wall was renovated and opened to the public, forming a popular tourist attraction. The wall runs for about 1,200 metres over Hushan.
Blue John is a semi-precious mineral, a form of fluorite with bands of a purple-blue or yellowish colour. In the UK it is found only at Blue John Cavern and Treak Cliff Cavern at Castleton in Derbyshire. During the 19th century, it was mined for its ornamental value, and mining continues on a small scale. Deposits of fluorite have been recently found in China with colouring and banding similar to the classic Blue John stone.

The mining industry of Yemen is at present dominated by fossil mineral of petroleum and liquefied natural gas (LNG), and to a limited extent by extraction of dimension stone, gypsum, and refined petroleum. Reserves of metals like cobalt, copper, gold, iron ore, nickel, niobium, platinum-group metals, silver, tantalum, and zinc are awaiting exploration. Industrial minerals with identified reserves include black sands with ilmenite, monazite, rutile, and zirconium, celestine, clays, dimension stone, dolomite, feldspar, fluorite, gypsum, limestone, magnesite, perlite, pure limestone, quartz, salt, sandstone, scoria, talc, and zeolites; some of these are under exploitation.
