The effect of octanol in cassiterite flotation using benzohydroxamic acid (BHA) as a collector was investigated. Theadsorption mechanism of octanol and BHA on the surface of cassiterite was analyzed by adsorption experiments and infrared spectraanalysis. Micro-flotation results indicated that single octanol exhibited almost no collecting power to cassiterite over a wide pHrange. However, as an auxiliary collector, octanol could markedly decrease the consumption of collector BHA and keep the recoveryof cassiterite in high level. The results of adsorption experiments and infrared spectra demonstrated that single octanol was notadsorbed on the surface of cassiterite. It formed adsorption connected with BHA on the surface of cassiterite, and enhanced thehydrophobicity of cassiterite. Octanol promoted the adsorption amount of BHA on the cassiterite surface, and decreased theconsumption of BHA.
