Gas dispersion properties of flotation systems, such as: bubble size (db), gas holdup (epsilong) and gas velocity (Jg) are became increasingly relevant in the past 10 years for optimization of flotation systems. Flotation system kinetics have been related to the bubble surface area flux (Sb), which is known to be derived from gas dispersion properties (Jg, db). Modeling of flotation systems and in particular flotation kinetics requires reliable measurements of Jg and to do this, two novel sensors were developed. The sensors collect bubbles by natural buoyancy, and relate gas flow to either accumulation of the gas bubbles (discontinuous technique) or the pressure drop across an orifice (continuous technique). Fundamental flow equations were ...
