• This study examined the effects of an additive, Bismarck Brown dye, on the crystallization kinetics of potassium alum crystals in a well-mixed continuous crystallizer. In the data analysis, size-dependent growth kinetics was assumed. The addition of Bismarck Brown dye depressed crystal growth and nucleation rates. The supersaturation of solution at steady state in the crystallizer increased as the Bismarck Brown concentration increased under the constraint of constant retention time and magma density. In this case the growth rate was enhanced but the nucleation rate was reduced. The predicted kinetic behaviors influenced by the addition of Bismarck Brown dye were in good agreement with the experimental results.
