2022, Journal of Molecular LiquidsCitation Excerpt :Thus, the copper activation and APTT hydrophobization contributed faintly to the floatability of pyrite.FeS2|Fe(III)(OH)x3-xCu(OH)i(APTT)j ↔ FeS2|Fe(III)(OH)x3-x + Cu(OH)i(APTT)j For sphalerite, the replace of surface Zn atom by Cu atom might firmly anchor Cu atom on its interface [30,55–58], and APTT reacted with the surface Cu atom to generate the Cu-APTT complexes [52–54] which hydrophobized sphalerite and dramatically promoted its floatability. The FTIR in Fig. 9 deduced that the pretreatment with FeCl3 and CuSO4 in sequence significantly weakened APTT adsorption on pyrite, while the adsorption of APTT on sphalerite was unmistakably observed.
