Fluorite is a nonrenewable mineral used to produce anhydrous hydrofluoric acid (AHF) and aluminum fluoride. The demand for low-grade fluorite powder (CaF2 < 97%) has fallen sharply owing to the current market conditions. Therefore, a large number of fluorite concentrates have been improved by acid leaching. While this approach can …

Introduction: The flotation machine is important for realizing the flotation process. It can process metal or non-metal minerals, such as copper, lead-zinc, lithium, antimony, fluorite, talc, etc. After the minerals undergo wet grinding, the minerals dissociated into monomers are adjusted into a slurry of a certain concentration.

For finely disseminated fluorite ore, froth flotation is the correct method. As mentioned earlier, the jig machine is the core equipment for fluorite ore upgrading. In this process, we use two different models of jig machines to processing the 0-8mm and 8-30mm fluorite ore respectively. ... AM30 jig machine for 8-30mm fluorite and LTA6109 jig ...

With the depletion of easily mined and separated wolframite, scheelite has become the primary source of tungsten. Flotation is the primary technique used to enrich scheelite. However, flotation separation of scheelite from calcium-bearing gangue minerals, such as calcite and fluorite, has always been challenging due to their similar surface …

The depressing properties of sodium polyacrylate (PA-Na) for scheelite and fluorite were studied by micro-flotation tests, infrared spectroscopy (IR), zeta potentials, X-ray photoelectron spectroscopy (XPS), and density functional theory (DFT). The flotation results reveal that the selective depression effect of PA-Na is better than that of sodium …
