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.
