Abstract
This paper studied the flotation recovery of KCl using a mixture of different carbochain amines as the collector in KCl flotation process. The results indicated that a much higher recovery of KCl was obtained through optimization of a mixed amine collector. Contact angle measurements revealed that mixed amine collectors further increased the hydrophobicity of the crystal surface of KCl. The solution surface tension could be reduced to 43 mN/m at 25 °C when the mixed amine was used. The aggregate size of mixed collector and the turbidity of the flotation solution showed that the dispersion of mixed amine colloids was better than that of octadecylamine collectors.
