Abstract


A review on the main residence time distribution (RTD) models currently applied to flotation is presented. Perfect mix, plug flow, N perfect mix reactor in series and the general combined model are included. In flotation diagnosis the most required model is the N non perfect mix reactor in series (NPRS). As an invariant physical meaning is usually assigned to the different shift in time and intensity of the peaks, wrong conclusion may arise with regard to the real mix state and correct scaling-up of the flotation recovery. In the present paper the above situation is overcome by integrating semibatch results in an analytical way, with the assistance of the García-Zúñiga and Klimpel equations for the recovery and the NPRS model for the mix state. Highly accurate predictions at industrial scale are obtained as compared to other methods.
