In the United States, fluorite is mainly found in Kentucky, Illinois, Missouri, and Colorado. Also, it is interesting to note that fluorite is actually considered Illinois' state mineral, and it has been mined in Southeastern Illinois since the early 1800s. It is a fluorspar-rich region and is called Illinois-Kentucky Fluorspar Mining District.

Experts consider it to be one of the largest fluorspar deposits in Europe. Fluorspar occurs in a mineral vein proven to a depth of at least 500 m and over a strike length of >1,200 m – with a thickness of up to 30 m. In addition, geothermal waters of >25 degrees Celsius occur in the pit, which can be readily used without complex drilling.

Now, directly treating acid-grade fluorspar with dipotassium hydrogen phosphate (K 2 HPO 4) under mechanochemical conditions affords a fluorinating reagent for direct S–F and C (sp 3 /sp 2 )–F bond construction, bypassing the need for HF production. Simple inorganic fluoride salts are often insoluble in the solvents that dissolve their ...

The United Kingdom-based Soy-Fujax Mining Company on Friday signed a Sh4 billion deal with Kenya to revive fluorspar mining in Elgeyo Marakwet County. The deal was signed by Mining and Blue Economy Cabinet Secretary Salim Mvurya, who was accompanied by his Principal Secretary Elijah Mwangi and Fujax UK Regional Director …

All fluorochemicals—including elemental fluorine and nucleophilic, electrophilic, and radical fluorinating reagents—are prepared from hydrogen fluoride (HF). This highly toxic and corrosive gas is produced by the reaction of acid-grade fluorspar (>97% CaF2) with sulfuric acid under harsh conditions. The use of fluorspar to produce …

Fluorite crystals formed 150–200 million years ago when hot water containing fluorine and other minerals was forced up through cracks in the earth where it interacted with the calcium-rich limestone bedrock. Crystals formed along cracks and in other open spaces in the rock. Fluorite (fluorspar) mining got its start in Illinois in 1842.
