| 摘 要： | 通过测定pH值、矿浆电位以及红外光谱, 探讨了丙三醇黄原酸钠抑制磁黄铁矿的作用机理。在丙三醇黄原酸钠作用下, 磁黄铁矿表面存在亲矿的-C==S吸收峰和亲水的-OH吸收峰, 抑制了磁黄铁矿的上浮; 磁黄铁矿的可浮性与pH值和矿浆电位存在着匹配关系, 在某一pH值下, 只有在适宜的电位区域磁黄铁矿才可浮。

| Abstract: | Through the investigation on pulp pH value, pulp potential and infrared spectra, the depression mechanism of pyrrhotite by glyceryl-xanthate sodium was discussed. The infrared spectra show that, under the influence of glyceryl-xanthate sodium, there are distinct absorption peaks of a mineral-avid group (-C==S) and a water-avid group (-OH) on pyrrhotite surface, which may depress the flotation of pyrrhotite. There is a matching relationship among the flotability of pyrrhotite and the pulp pH value and potential as well, while, for a certain pH value, pyrrhotite can only be floated in a suitable range of pulp potential. |
