The Illinois-Kentucky ore district hosts the largest deposits of fluorite in the USA. A long-standing hypothesis for the formation of the Illinois-Kentucky deposits is that the ore fluid was a sedimentary brine infused with F-rich fluids exsolved from Permian ultramafic magmas. This ore fluid may have had a F concentration between 680 and …

Hydrothermal ore-forming systems were simulated at the bench-top scale using columns packed with apatite, fluorite or a 1:1 mixture of each. These columns were heated to 250 °C and REE-bearing ...
A source of calcium fluoride is fluorite ore containing 96.0 wt% CaF, and 4.0% SiO2. In a typical hydrofluoric acid manufacturing process, fluorite ore is reacted with 93 wt% aqueous sulfuric acid, supplied 15% in excess of the stoichiometric amount. Ninety-five percent of the ore dissolves in the acid.
Separation of scheelite from calcite and fluorite. Commonly used thick slurry high-temperature method. First, concentrate the pulp to a concentration of 60~70%, then add water glass, heat the pulp to above 80°C, stir for 30-60 minutes, then dilute with water, and flotate scheelite at room temperature. The product in the tank is Fluorite and ...
