Sodium Fluoride (Feldspar Flotation Activator)
CAS Number: 7681-49-4
Sodium Fluoride is an activator used in the flotation of feldspar, quartz, and other silicate minerals, particularly in HF-based flotation circuits for the beneficiation of feldspar-quartz sand mixtures. Fluoride ions selectively activate feldspar surfaces over quartz, enabling their differentiation using amine collectors. Sodium Fluoride is also used as a pH modifier and activator in fluorite and phosphate ore flotation, and as a corrosion inhibitor in processing equipment.
