The invention discloses an anion and cation combined collecting agent and application of the anion and cation combined collecting agent in andalusite flotation. The anion and cation combined collecting agent is prepared by mixing anion sodium dodecyl sulfate and cation N-dodecyl ethylenediamine. The adsorbent has the characteristics of good water solubility, strong selective adsorption capacity on andalusite minerals and the like. Particularly, when the mass ratio of the andalusite to the quartz to the biotite is 1: 4, the recovery rate difference of the andalusite, the quartz and the biotite reaches more than 65%, the synergistic factor is greater than 1, and the andalusite and associated minerals thereof can be separated, so that the enrichment of the andalusite is realized. 本发明公开了一种阴阳离子组合捕收剂及其在浮选红柱石中的应用。所述阴阳离子组合捕收剂由阴离子十二烷基磺酸钠和阳离子N-十二烷基乙二胺混合制成。具有水溶性好，对红柱石矿物的选择吸附能力强等特点。特别是在其质量比为1:4时，红柱石与石英和黑云母的回收率之差达到了65％以上，协同因子大于1，可以实现红柱石与其伴生矿物的分离，从而实现对红柱石的富集。
