摘　　要：研究了不同条件下捕收剂油酸钠对明矾石、地开石单矿物浮选回收率的影响,油酸钠在明矾石、地开石单矿物表面的吸附情况,以及油酸钠在明矾石、地开石表面的红外光谱分析等。确定了油酸钠体系下明矾石、地开石的浮选分离条件,证明了油酸钠在明矾石、地开石表面同时存在物理吸附和化学吸附。This paper studied the effect of sodium oleate on single mineral flotation of dickite and alunite in the different conditions,flotation separation condition,and the agent absorption on the mineral ＇s surface.The dosage of sodium oleate and the type of absorption are confirmed by the FT-IR spectrum analysis.Comparing the agent saturated adsorption capacity shows that sodium oleate can be used as the collector for alunite and dickite flotation separation.In the processing,the dosage must be strict controled.
