Many industrial processes involve reaction between the two immiscible liquid systems. It is very important to increase the effciency and productivity of such reactions. One of the important processes that involve such reactions is the metal-slag system. To increase the reaction rate or effciency, one must increase the contact surface area of one of the phases. This is either done by emulsifying the slag into the metal phase or the metal into the slag phase. The latter is preferred from the stability viewpoint. Recently, we have proposed a simple and elegant mathematical model to describe metal emulsifcation in the presence of bottom gas bubbling. The same model is being extended here. The effect of slag and metal phase viscosity, density and metal droplet size on the metal droplet velocity in the slag phase is discussed for the above mentioned metal emulsifcation process. The models results have been compared with experimental data.
