“…After adding GA, a new carbon-oxygen double bond peak appears at 288.55 eV in the C 1s spectrum of dolomite, and the peak area of the carbon-oxygen single bond at 286.30 eV is larger than that of the raw ore. 33 In addition to the characteristic peaks of original carbonates and hydroxyl oxygen, the characteristic peaks of Ca/ Mg-O at 531.2 eV are detected in the O 1s spectra of the dolomite surface after GA action. 36 Additionally, the peaks of carbonates and hydroxyl oxygen on the dolomite surface are observed to shift by 0.09 eV and 0.1 eV towards higher energy levels, respectively. The Ca 2p peaks of dolomite at 347.26 eV and 350.88 eV (Ca 2p 3/2 and Ca 2p 1/2) increase by 0.15 eV and 0.12 eV, respectively, after GA treatment.…”
