Abstract/Summary A major impediment to the development of computer models for Bayer precipitators has been the poor understanding of A1(OH)3 (gibbsite) agglomeration, which is the major size enlargement process during Bayer precipitation. Recent studies claim to have identified a size-independent mechanism for gibbsite agglomeration in synthetic caustic aluminate liquors. This paper uses these latest findings on the agglomeration kinetics in the development of a population balance model for gibbsite precipitation. The model gave reasonable agreement to experimental data from a 2.8 litre continuous precipitation unit.
