For the flotation of impurities from quartz sand, Aero 3030C was better than a combination of R 825 and Armak C. When Aero 3030C was used, a higher quality of quartz sand concentrate was obtained than when a combination of these collectors was applied. The mass recovery of quartz sand was almost the same: 64.47% when Aero 3030C was used and 61.72% when a combination of Aero 825 and Armac C was used.
