First described in 1797 by Carlo Antonio Galeani Napione, its name comes from the Latin fluere, meaning “to flow,” a nod to its use as a flux. It is the principal source of fluorine and a familiar ingredient in hydrofluoric acid production.\u003cbr\u003e\u003cbr\u003eXianghualing Mine is part of the Xianghualing Sn-polymetallic ore field in Linwu County, Chenzhou, Hunan, China, where it sits in a district known for skarn-type tin-lead-zinc mineralization. The locality is noted for substantial metal endowment, with estimated resources of about 134,000 tons of tin and 178,000 tons of lead-zinc. For collectors, it is especially significant as a productive Chinese locality that has yielded a broad suite of minerals, including cassiterite, scheelite, natrolite, and hsianghualite.\u003c\/p\u003e","brand":"Crystal Castle","offers":[{"title":"Default Title","offer_id":49692346384539,"sku":null,"price":23.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0336\/3012\/6217\/files\/92e6acda-aeb3-4928-9b09-3cb6fd6ce82a.jpg?v=1790799860","url":"https:\/\/www.overtonfamilyjewels.com\/products\/fluorite-corner","provider":"OFJ's Crystal Castle","version":"1.0","type":"link"}
