摘　　要：通过单矿物浮选、总有机碳-有机氮测试(TOC-TN)和Zeta电位测试等方法,系统研究了阴离子捕收剂十二烷基磺酸钠(SDS)和阳离子捕收剂十二胺(DDA)在白云母、钾长石、石英和斜绿泥石表面的吸附行为。结果表明,SDS和DDA组合使用时,在大范围pH区间内,对白云母表现出优良的选择性;且两者在各矿物表面吸附量均出现大幅度变化;SDS会显著抑制DDA在钾长石、石英和斜绿泥石表面的吸附,对白云母的影响相对较小;DDA能大幅加强SDS在白云母表面的吸附,同时显著削弱SDS在斜绿泥石表面的吸附。To study the adsorption behavior of the anionic collector sodium dodecyl sulfate(SDS)and the cation collector dodecylamine(DDA)on the surfaces of muscovite,orthoclase quartz and clinochlore through pure mineral floatation,TOC-TN analysis,Zeta potential analysis.Use the combined SDS-DDA as the muscovite collector,the selectivity of the collector is eminent and stable in a large-scale pulp pH value.Furthermore,on each mineral surface,the adsorption capacity of SDS and DDA will change significantly.The SDS had strongly inhibited the adsorption of DDA on the surfaces of orthoclase quartz and clinochlore,but the impacts of muscovite were fewer.Conversely,the DDA improved the adsorption of SDS on the surfaces of muscovite obviously,on the other hand,the adsorption of DDA on the surfaces of clinochlore was weakened visibly.
