Despite a significant number of studies having been carried aimed at developing strategies
for scale inhibition during the Bayer process, particularly in heat exchanger systems, there is
still limited understanding of the underlying mechanisms and kinetics of scaling, in particular
for single stream plants. The aim of this study was to further this understanding for sodium
aluminosilicate crystallisation in spent Bayer liquor seeded with gibbsite. Gibbsite is present
in pre-desilicated bauxite which is mixed with spent liquor and then passes through the heat …
