Computational Modelling of Gas Dispersion Parameters in Froth Flotation

Computer techniques were used as a technical means to perform numerical calculations on froth flotation. It is a methodology that uses electronic computers to solve froth flotation problems through numerical calculations. Gas dispersion properties include bubble size, gas holdup, bubble surface area flux and input power are effective parameters on flotation performance. During the last ۱۰ 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. According to these equations, most effective variables are impeller peripheral speed, superficial gas velocity and pulp density, respectively.
