Numerous flotation tests have been made on a variety of fluorspar ores containing from none to as much as 70 percent barite using the combination of sodium fluoride and lignin sulphonates to retard the barite. All of the ores responded, readily to our method of flotation and yielded acid grade fluorspar concentrates essentially free of barite.

Apr 01, 2021 High-grade fluorite is the primary source of hydrofluoric acid. Due to the increasing demand flotation, the central processing technique to obtain high-grade fluorite, has attracted extensive attention. However, due to gangue minerals associated with fluorite, such as quartz, calcite, and barite, fluorite flotation remains challenging.

Mar 25, 2015 Abstract. Different dispersants were added in the dispersion process to improve the efficiency of fluorite flotation. The types and dosage of dispersant on the improvement of fluorite flotation were investigated when the sodium polyacrylate SPA was used as the dispersant and its addition is 0.5, the concentrate grade of CaF 2 increased from 90 to 98 and the fluorite recovery
