Mineral Resource of the Month: Fluorspar
The term "fluorspar" refers to crude or beneficiated material that is mined and/or milled for the mineral fluorite (calcium fluoride). Fluorite is a nonmetallic mineral, containing 51.1 percent calcium and 48.9 percent fluorine. Industry practice has established three grades of fluorspar: acid grade (containing more than 97 percent calcium ...

Industrial minerals: Separation technology for the highest …
This extremely strong magnetic field enables industrial minerals such as limestone or kaolin to be upgraded further. For the smaller grain sizes of up to 5 mm, the higher degree of breakdown results in higher qualities. Salts can also be upgraded or cleaned by this method, by the separation of clay-containing contaminants.

Process intensification: An electrochemical perspective
In the centrifugal field, the mixture of gas and electrolyte rotates at the same speed as the cell body and a rapid bulk radial flow of the gas bubbles is inwards to the axis. The mathematical model was developed to examine the influence of centrifugal fields on the electrochemical behaviour of the rotary cell with gas evolving electrodes.

General Features of Colorado Fluorspar Deposits
fluorspar. As early as the 1870's, fluorspar was mined in small amounts near Evergreen and carted to Central City, where it was used in smelting the ores of precious metals. In 1873 or 1874, the first shipment of fluorspar from the Jamestown district was reported. Output was small and probably sporadic until 1903
