This paper introduces and discusses some potential effects of dilution in aqueous precipitation processes. The response of a sulfate solution comprising of 0.3 mol L-1 Zn and 0.015 mol L-1 Ni diluted with NaOH solution has been simulated. Considerable changes in separation pH, separation potential, and precipitating minerals have appeared after dilution. An increase in separation pH from 6.86 to 7.45 due to 100 times dilution has been predicted. It has also been revealed that the selectively precipitable zinc decreases from 89.4 to 85.7 % as a result of dilution. The products of zinc precipitation from undiluted and 100 times diluted solutions should be ZnO and Zn4(OH)6SO4, respectively, according to equilibrium analysis. Despite the acceptable agreement of experimental results, the full agreement has been restricted in some cases by kinetic difficulty of ZnO precipitation and local high pH zone effect that has led to nickel co-precipitation.
