Fluorspar mining and milling in southern Illinois
"Fluorspar is fully as necessary a material in certain phases of steel manufacturing as the metal that enters the furnace. Without it, the basic open hearth practice probably would not have reached its dominant position among steel-making methods. Of the entire output of fluorspar, 80 to 85 percent is used in basic open-hearth and electric furnaces as a flux and …

Methods Of Fluorspar Exploration
Although fluorspar is considered an industrial mineral by usage and value, its geological occurrence and the mining and milling methods employed make it more akin to the non-ferrous metal ores. Likewise methods of exploration for it are more like those used in the search for lead and zinc, with which fluorspar is often mixed. In fact, it often takes the mixture of fluorspar, …
