Fluorite crystallized at minimum temperatures of 70 to 110 °C, 10–40 °C warmer than the host Triassic sedimentary rocks. Ascending brines were expelled during the Early Cretaceous and experienced a drop in pressure and temperature, together with possible mixing with the SO4-rich pore water of the sedimentary rocks, causing precipitation of ...
Quartz-Fluorite Ore Flotation Flowsheet. This process is used for the separation of fluorite ore whose associated impurity minerals are mainly quartz. The crystal size of fluorite is extremely uneven, ranging from a few microns to tens of millimeters, and it is closely symbiotic with quartz. Other impurity minerals include calcite, pyrite, and ...
