The open-hearth steel furnace process, which was introduced in the 1880s, used fluorite for flux, increased demand considerably, and large-scale mining for fluorite began in Illinois soon after. In 1890 the Fairview Mining Company began mining fluorite, and in 1893, the property was purchased by the Rosiclare Lead & Fluorspar Mining Company.
An Environmental Assessment process was commenced in 2014 with the intent of resuming mining activities. New employment opportunities with CFI (as part of the St-Lawrence Fluorspar Project) were advertised in the fall of 2018. Some important reminders of the town's mining heritage remain.

But by 1990, more than 90% of the fluorite used in the U.S. was imported. Illinois was the only remaining domestic producer. Competition from foreign producers coupled with high costs of underground operations made Illinois' fluorspar mining unprofitable. The last fluorspar mine in Illinois closed in December 1995.

Fluorspar is used directly or indirectly to manufacture products such as aluminum, gasoline, insulating foams, refrigerants, steel, and uranium fuel. Byproduct fluorosilicic acid production from some phosphoric acid producers supplements fluorspar as a domestic source of fluorine, but is not included in fluorspar production or consumption calculations.
Fluorspar occurs in a variety of mineral deposits and is mined either as a main commodity or as a coproduct of metal mining, according to the British Columbia Geological Survey (BCGS). The recovery of fluorspar from metal-type mineral deposits adds to capital and processing costs.
