  • Publication number: 20230406717
    Abstract: A process for extracting fluoride from a solution of high pH comprising more than 0.1 mol of alkaline hydroxide and/or alcoholate per liter dissolved in a polar solvent is described. The polar solvent is chosen from water, lower alcohols, and mixtures thereof. The process is characterized in that the solution liquid is contacted with a solid phase adsorbent chosen from a) alkaline earth salts comprising carbonate anions, oxo anions, sulphate anions, or phosphate anions, and alkaline earth salts comprising a mixture of such anions or a mixture of such anions with hydroxyl anions, and b) cation binding resins loaded with one or more 3-valent cations, chosen from 3-valent cations of Al, Ga, In, Fe, Cr, Sc, Y, La and lanthanoides.
