Numerical and experimental study of the effect of a froth baffle

2015/06/01 · Experimental description Flotation tests were done using an artificial ore made up of 80% silica as gangue and 20% limestone as floatable component in a closed loop flotation circuit shown in Fig. 1. These experiments were done to compare the effect of a froth baffle on flotation performance i.e. limestone recovery and grade.

Froth flotation is a complex physicochemical process that is accomplished in two distinct phases in a flotation cell: a pulp phase and a froth phase. The pulp phase is a mixture of an aqueous suspension composed of finely ground particles of ore minerals, water and air bubbles, along with dissolved chemical species such as frother, collector, etc.
