本研究采用第一性原理计算研究了黄药氢(HOCS2−)与黄铁矿(10 0 0)和方铅矿(10 0 0)表面的相互作用。计算结果表明,HOCS2−在黄铁矿(1 0 0)表面Fe位点发生强烈的化学吸附,而在方铅矿(1 0 0)表面Pb位点的相互作用较弱。黄原药与氧化黄铁矿表面的相互作用减弱,而与氧化方铅矿表面的相互作用增强。讨论了黄原酸盐与矿物表面的水化作用。黄铁矿表面可形成二氧原,方铅矿表面不能形成二氧原。
In this study, first-principles calculations were performed to investigate the interactions of hydrogen xanthate (HOCS2−) with pyrite (1 0 0) and galena (1 0 0) surfaces. The calculation results suggest that strong chemisorption of HOCS2−occurs at Fe sites on the pyrite (1 0 0) surface, whereas its interaction at Pb sites on the galena (1 0 0) surface is weak. The interaction of xanthate with oxidized pyrite surface is weakened while the interaction of xanthate with oxidized galena surface is enhanced. The hydration of xanthate and mineral surfaces is discussed. Dixanthogen could be formed on the pyrite surface but not on the galena surface.
