摘要: 采用Tafel曲线、交流阻抗法，研究了铁闪锌矿与浮选药剂相互作用的界面电化学行为。结果表明：pH对铁闪锌矿的腐蚀电位几乎无影响，但随着pH增大，腐蚀电流增大，矿物表面的疏水性元素S0急剧减少，羟基化作用变大；二乙基二硫代氨基甲酸钠是铁闪锌矿的腐蚀剂和浮选抑制剂，Ca（OH）2在成本和性能上，都是碱性浮选介质中最佳的pH调整剂。

关键词 ：铁闪锌矿, 浮选药剂, 腐蚀电化学

Abstract：The interfacial electrochemical behaviors of the interaction of marmatite with flotation reagents in 0.1mol/L KNO3 media were studied by potentiodynamic and impedance measurements. The results indicated that the corrosive potential of marmatite almost is not affected by pH values, but its corrosive current rises, and hydrophobic sulfur on marmatitie surface decreases rapidly and hydro action becomes obvious with the rising of pH values; that diethyl dithiocarbamate is a corrosive reagent and an inhibitor for the flotation of marmatitie;Ca(OH)2 is the best reagent for adjusting pH in alkaline flotation system.

Key words： marmatite flotation regent corrosive electrochemistry
