There is currently no standard approach to laboratory flotation testing and interpretation. The deficiency stems, in part, from the difficulties in quantifying the recovery of mineral particles by hydraulic entrainment (R-e) and the recovery of collected mineral particles across the froth zone (R-f) of a laboratory flotation cell. For lack of alternatives, most practitioners ignore entrainment (R-e = 0) and assume that froth recovery is 100% (R-f = 1). Consequently, differences in test scraping frequency or froth characteristics can lead to large differences in the inferred collection kinetics. This paper proposes resolving the problem by incorporating a phenomenological solution for R-e and R-f . By considering the test water balance, incorporating hindered settling theory, and making some simple assumptions regarding the pulp, interface, and froth phases, it can be shown that the entrainment recovery of any mineral can be calculated solely from the particle size and specific gravity. A similar approach can be used to estimate the froth recovery as a function of time. The method is applied to a data set of flotation tests conducted with different scraping rates, and it is demonstrated that it yields similar flotation rate constants regardless of the scraping rate.
