Abstract/Summary The kinetic model for leaching process of Chinese diaspore with particle size distribution has been studied. This paper takes into account 1) the irregular shape and rough surface of the natural particles, 2) the residual concentration of Al in particles due to the impurities in natural diaspore, and 3) the particle size distributing in a size range and varying with digesting time. A new kinetic model, PSD+RC+F model, has been developed by the real characteristics of natural bauxite particles in leaching process. The modified gamma distribution function was applied to describe the particle size distribution of diaspore particles. PSD+RC+F model combined with gamma-like distribution function, validated by numerical analysis, shows good agreement with the experimental data.
