2020-3-1  The interference of gangue minerals during the flotation process of low rank coal was extremely complicated. The X-Ray photoelectron spectroscopy (XPS) technique was used to excite the inner electrons (or valence electrons) of atoms or molecules in a sample using radiation, and the photoelectrons generated by the excitation were measured.
