系统地研究了辰砂在黄原酸体系中的可浮性和常见重金属离子对其可浮性的影响。结果表明,黄药易捕收辰砂,硫酸铜和硝酸铅对辰砂稍有活化作用,三价和二价铁盐对辰砂有抑制作用,硫酸锌对它的可浮性影响较小。通过红外光谱、X—光电子能谱、原子吸收光谱和ζ—电位测定等方法研究了辰砂表面电性、辰砂与硫酸铜和黄药及活化的辰砂与黄药的作用机理。
The flotation of cinnabar in xanthogenic acid system and the influence of common heavy metal ions on its floatability were studied systematically. The results showed that the xanthate easy to capture cinnabar, copper sulfate and lead nitrate on the cinnabar activation, trivalent and ferric salts on the cinnabar inhibit zinc sulfate on its buoyancy less affected. The effects of cinnabar on the surface electrical properties, cinnabar and copper sulfate and xanthate and activated cinnabar and xanthate were studied by means of infrared spectroscopy, X-ray photoelectron spectroscopy, atomic absorption spectrometry and ζ-potential measurement.
