摘要	The crystallization kinetics of Mg-borates from different diluted brines was investigated by dynamical method. With the aid of simple optimum method and Runge-Kutta digital solution of differential equations, the experimental data was fitted by computer and the optimum kinetic equations of Mg-borates were obtained. Factors such as temperature, mass dilution ratios and boron concentrations during crystallization were tested. The crystallization rate was also calculated based on the kinetic equations. The results show that low temperature, high boron concentration and medium dilution ratio favor the Mg-borates crystallization. The boron yield would be more than 88% in B2O3 under the optimized condition. The kinetic parameters indicate that almost all of the crystallization mechanisms of Mg-borates in diluted brine are polynuclear layer controlled growth. Besides, the crystallization reactions in diluted solutions were also proposed.
