a concentrating mill was constructed at the mine site to separate ˛uorspar from waste rock.5 Wagons originally transported the ˛uorspar concentrates to the Denver & Rio Grande Rail-road siding at Wagon Wheel Gap. In July 1917, the company constructed a surface tram track along the east side of Goose Creek from the mill to the rail siding.
During the concentrating processes, part of the fluorspar in the crude ore is dissolved and discharged in the mill effluent. Some fluoride is also contained in the discharges from the fluorspar mines. The two counties in which the fiuorspar industries operate are described as two of the smallest and most sparsely populated counties in Illinois.
The mean fluoride concentration was 4.7 mg/liter (range 2.4–11.7 mg/liter), which exceeded their postshift concentration by 0.2 mg/liter. These results indicate that the low aqueous solubility of fluorspar reduced the biologic availability of the fluoride ion but that this did not prevent excessive fluoride absorption in some workers.

The Vergenoeg Fluorspar Mine is in Limpopo, South Africa. Production output of the Vergenoeg Fluorspar Mine was considered to be small size. The ore mined is composed of hematite and fluorite with waste material consisting primarily of feldspar. The ore body is described as tabular shaped and is found 30 meters (98 feet) below the surface.
Tailings are produced as a byproduct of milling, and exist essentially as sand depleted of valuable mineral. The objective of tailings management is to confine the mill tailings and provide safe, long-term, low maintenance disposal. Tailings are stored in engineered structures called tailings impoundment areas, which can be created through the use of dams, berms, … Continued
