通过动电电位测定、吸附量测定、红外光谱分析及单矿物浮选等手段,研究了油酸在石英和长石表面的存在状态及吸附作用.结果表明,油酸以两种方式吸附:油酸根离子的静电吸附和油酸分子的物理吸附.在长石表面还存在油酸根离子与铝离子之间的化学吸附 因此,油酸在长石表面的吸附强度高于石英.试验还表明,在抑制剂的配合下,油酸钠可以活化阳离子胺类捕收剂对长石的捕收
The sdsorption behaviour of sodium oleate on quartz or feldspar has been ex-amined by zeta-potential and adsorbabilty measuremant, together with IR spectral analysesand flotation tests. Both electrostatic adsorption with oleate ions and physical one with oleatemolecules were occurred on quartz. While on feldspar, the chemical adsorption was con-ducted between oleate ions and Al. Thus, the adsorbability on feldspar is superior to that onquartz. The sodium cleate is able to activate feldspar flotation with amine as collector.
