The function mechanism among the minerals and floatation drugs had been studied with the way of IR and academic calculation, which pointed out that absorption of G-4 on the surface of phosphorite belonged to physical and chemical types, but the chemical one was in the highest flight. Absorption of amine collector named GE-609 on the surface of quartz belonged to electrostatic and physical type. Distilled water could hardly wash the GE-609 down from the surface of quartz. Leading component of S-721 was the concentrated compound of naphthol sulfonic acid and formaldehyde. The compound had a stronger affinity to the Mg~(2+) on surface of dolomite than the Ca2+ on surface of phosphorite, which is the essential reason in the separation of phosphorite and dolomite. The leading components of soluble glass in function were HSiO3 hydronium and F^SiC^ colloid granule.

通过红外光谱测定以及理论计算的方法研究了选矿药剂与矿物间的作用机理，研究表明：脂肪酸捕收剂G-4对胶磷矿的捕收作用是以化学吸附为主、化学吸附与物理吸附共同作用的结果；胺类阳离子捕收剂GE-609在石英表面的吸附属于静电物理吸附，但很难用水洗的方法使GE-609从石英表面脱附；S-721主要成分为萘酚磺酸与甲醛的缩合物，萘酚磺酸与甲醛的缩合物对白云石表面Mg~(2+)的吸附明显强于对胶磷矿表面Ca~(2+)的吸附，这是胶磷矿与白云石分离的根本原因；水玻璃溶液中对石英起抑制作用的主要组分是HSiO_3~-和H_2SiO_3胶粒，水玻璃除对石英起抑制作用外，对矿浆还具有一定的分散作用。
