Fine cassiterite and quartz were separated by liquid-liquid extraction using iso-octane as an oil phase, dodecylamine acetate (DAA) as a collector, and sodium chloride as a depressant. With regard to the distribution of fine cassiterite and quartz between oil and aqueous phases, the effect of DAA was investigated in terms of pH, DAA and NaCl concentrations, zeta potential, and adsorption d. A maximum recovery of cassiterite in the oil phase was obtained with pH around 6.0, DAA concentration of 1.0 ¡Á 10-5 mol/L, and NaCl addition of 0.1 mol/L. In these conditions of liquid-liquid extraction, most of the fine quartz remained in the aqueous phase. Thus NaCl was an effective depressant for fine quartz under optimum conditions. A series of separation tests by liquid-liquid extraction was then conducted for the mixed samples (6.0% Sn) of cassiterite and quartz. By a single separating process, the recovery of cassiterite in the oil phase was about 92% with a grade of 27% Sn. The same results could also be obtained by using kerosine in place of iso-octane as the oil phase.
