Frothers are non ionic surfactants, commonly alcohols and polyglycols, used to provide two functions in flotation, namely to reduce bubble size and stabilize froth. Both functions imply an impact on the properties of the air-water interface (bubble surface) but there is no consensus on the mechanism, particularly with regard to bubble size reduction. Blending frothers is becoming common in flotation practice arguably enhancing performance by permitting independent control of the two frother functions. However, there have been no studies to determine this blend possible action. The blends used here focused on a small addition of polyglycol (F150 and DF250) to alcohols (1-pentanol and MIBC). The effect of blends on gas dispersion properties (...
