Evaluation of Sulfonate-Based Collectors with …

 &#; This investigation aims to demonstrate the effects of hydrophobic tails on the affinity and relevant flotation response of sulfonate-based collectors for fluorite. For this purpose, a series of alkyl sulfonates with different hydrophobic tails, namely sodium decanesulfonate (C), sodium dodecylsulfate (C), sodium hexadecanesulfonate (C), and sodium dodecylbenzenesulfonate (CB) were applied.

Separation Mechanism of Fatty Acids from Waste …

 &#; Using the mixed fatty acids (MFA) produced by waste cooking oil as flotation collectors directly, the flotation effect is usually not satisfactory, especially at lower temperature, which may be due to the presence of large amounts of saturated fatty acids. In this study, waste cooking oil was separated into saturated fatty acids (SFA) and unsaturated fatty acids (UFA).
