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
