    这类捕收剂不含氮也不含硫，是以高度不饱和的炔基为主体的碳氢化合物。起初是用含炔基的缩醛类或醇醚类，随后又发展成丙炔醇和叔十二烷基硫—1—丁烯—3—炔。它们可用为硫化矿的捕收剂。

    另外，选矿药剂的混合使用也是浮选药剂发展的有效途径。有学者提出“混合用药及其协同效应”的观点，并通过了大量的试验加以证明。例如硫氮腈酯与2号油按一定比例混合，其选矿指标并不低于单独使用硫氮腈酯，从而可以降低选矿成本。铅锌矿在浮铅循环中将柴油与黄药混用，获得优于单独使用乙黄药或丁钠黑药的指标，铅精矿品位与回收率都有不同程度的提高。将塔尔油与亚磺酸铵混合作为捕收剂，在矿石充分解离与软化水的条件下，对铁矿石表现出的较强的捕收能力与较好的选择性。在国外，混和用药的研究已获得较好结果，并取得许多专利。据文献报道，两种不同的浮选药剂按一定比例混合时，有时会在回收率曲线上出现一个高峰值，比单独使用任一种药剂的效果都好。
