Abstract
This paper evaluates frother performance by studying two-phase gas-liquid system. Surface tension, foamability, foam stability and bubble size distribution are measured as a function of ft-other type, frother dosage, and sol-ution pH. Variation of bubble size with respect to frother
concentration is used for predicting the critical coale-scence concentration (CCC) of selected alcohol and poly-glycol ether family frothers. An inverse relationship is found between critical coalescence concentration and dynamic foamability index (DFI). Df-1012 and PPG are found
to be more powerful in terms of stability, foamability and CCC than frothers belonging to alcohol family. Frother effectiveness is found to be relatively better in alkaline pH.
