The Empirical Prediction of Gas Dispersion Parameters on Mechanical Flotation Cells

Abstract

Gas dispersion properties include bubble size (32), gas holdup (d g ) and bubble surface area flux (b) and input power () are effective parameters on flotation performance. During the last 10 years, some investigations have been carried out to measure these parameters in mechanical flotation cells. In this research, some models are created to estimate gas dispersion properties and input power by experimental data. Variables of models are impeller peripheral speed (S P s N), superficial gas velocity (g J) and pulp density () and final form of models are d P    J 0.486 0.012 32
