The addition of frother in flotation has two main functions, to help reduce bubble size and help produce a stable froth. A role of frother on bubble behavior in pulp zone is usually not considered. A previous study showed that as frother type was changed the same gas holdup was given by different size bubbles. This implies that bubble rise velocity depends on the nature of the surfactant (frother type). A study using bubble swarms appears to support the frother type effect but bubble interactions are a possible confounding factor. This study resolved the question by measuring terminal rise velocity profile of single bubbles (ca. 1 to 2 mm) as a function of frother type. It is shown that at the concentrations of interest...
