Hydrophobic behavior of fluorite surface in strongly

2021-1-20  Surface roughness is related to surface wettability: the rougher mineral surface is, the more hydrophilic the hydrophilic surface is and the more hydrophobic the hydrophobic surface is. AFM measurements confirm that the fluorite surface becomes hydrophobic under strongly alkaline conditions and that increased roughness enhances the surface floatability by increasing the surface hydrophobicity.
