The results showed that for flotation of feldspars, Aero 3030C performed better than Flotigam DAT. Aero 3030C was more
selective, and with its application a higher mass recovery of feldspar was obtained. In particular, the mass recovery of feldspar was 19.58% when Aero 3030C was applied and 7.58% when Flotigam DAT was used. However, the chemical compositions of the feldspar concentrates were not significantly different no matter which of these reagents was used.
