16.1.2 Frothers. Frothers are surfactants, usually organic heteropolar compounds such as alcohols or polyglycol ethers. Due to the heteropolar nature, the frother adsorbs at the air/water interface and as a result, lowers the water surface tension. This has the effect of producing smaller bubbles and more importantly it stabilises the froth ...Web

Bubble size dictates the carrying capacity of a flotation machine. Finer bubbles increase the carrying capacity (often measured as the mass flow rate (tonne/h) of concentrate per m2 of surface area of the flotation machine) as there is more bubble surface area per volume of air added for particles to attach. Essentially, this meansWeb
