The growth of acicular iron oxyhydroxide crystals during the alkaline process was studied. On the basis of experiments, the nucleation and growth process of crystal particles during the reaction were investigated. The effect of initial oxidation rate on the final crystal product index was investigated. The effect of different aging processes on the crystal products was also studied.
