Determination of Floatability Data Using the Emdee™ Microflot Method

The discovery of the particle — bubble attachment/detachment equilibrium in a vigorously agitated closed mineral/reagent system offers new research opportunities for the flotation scientist. This mechanical/ thermodynamic equilibrium offers a potential link between thermodynamic principles and the performance of continuous flotation systems. The set of subsequent equilibria determined on the head sample by this method constitutes a mineral floatabi- lity spectrum for a given ore/reagent system. The results relate to flotation rate constants in a batch cell, so these data may be used for prediction of batch cell kinetics.
