摘　　要：氨基三亚甲基磷酸(ATMP)是一种被广泛使用的表面活性剂。为探究ATMP作为一种潜在的闪锌矿抑制剂实现闪锌矿和方铅矿浮选分离的可能性。通过微浮选试验,探究了ATMP在闪锌矿和方铅矿浮选分离过程中的作用效果,同时采用接触角测定、溶液化学计算、Zeta电位检测以及XPS分析,研究了ATMP对闪锌矿的选择性抑制机理。微浮选试验结果显示,ATMP作为一种潜在的闪锌矿抑制剂具有实现闪锌矿和方铅矿浮选分离的潜力。接触角测定结果表明,ATMP能显著提升闪锌矿的表面润湿性。Zeta电位检测结果表明,经ATMP处理后,闪锌矿表面正丁基黄药(SBX)的吸附量显著降低。XPS分析表明,ATMP在闪锌矿表面的吸附与其分子中的膦酸官能团有关。ATMP作为一种潜在的闪锌矿抑制剂具有实现闪锌矿和方铅矿浮选分离的潜力。Amino Trimethylene Phosphonic Acid(ATMP)is a commonly utilized surfactant.The objective of this paper is to explore the viability of ATMP as a potential depressant for sphalerite,enabling the flotation separation of sphalerite and galena minerals.In this study,the role of ATMP in the flotation separation of sphalerite and galena was investigated through micro-flotation experiments.Moreover,the selective inhibition mechanism of ATMP on sphalerite was investigated using contact angle measurements,solution chemistry calculations,Zeta potential detection,and XPS analysis.The micro-flotation test results demonstrated the(ATMP)as an potential inhibitor for achieving the flotation separation of sphalerite and galena.The contact angle measurement results indicated that ATMP significantly improved the surface wettability of sphalerite.Furthermore,Zeta potential detection revealed a remarkable decrease in the adsorption of SBX on the surface of sphalerite after ATMP treatment.XPS analysis indicating that the adsorption of ATMP on the surface of sphalerite is related to its phosphonic acid functional groups in the molecule.As a potential depressant for sphalerite,ATMP holds promise in facilitating the successful flotation separation of sphalerite and galena minerals.
