“…Based on the phases present in the samples in this work, the amorphous fraction determined is likely overestimated due to microabsoption.

“…This method was time consuming and the manual refinement suffered from poor reproducibility issues. In Hodge et al (2018), the TOPAS software was used to perform a full profile fit using Rietveld refinement (Loopstra and Rietveld 1969;Rietveld 1969;Coelho 2018). In the present work, fundamental parameters, as opposed to empirical models were used for modelling the peak shapes resulting in better peak fitting for asymmetrical peaks (Cheary and Coelho 1992).…”

Reactive silica in bauxite is a key challenge for the alumina industry due to the associated losses of sodium hydroxide and alumina associated with processing this impurity. The bauxite residue sinter leach process (BRSLP) is a potential method of recovering sodium hydroxide and alumina from bauxite residue. In this research, bauxite residue lime sinters were characterised using a combination of quantitative X-ray diffraction in conjunction with scanning electron microscopy as well as for leaching performance. It is shown that sintering reactions proceed at a significantly faster rate than previously reported which has a positive implication for industrial application. A new set of reactions and reaction pathways are proposed which describe bauxite residue lime sintering in greater detail than previously possible.
