Recovery of sodium from alumina-extracted fly ash using concentrated sodium carbonate solution [PDF]
A novel method for the recovery of sodium from alumina-extracted fly ash (AEFA) using concentrated Na2CO3 solution is presented. Sodium was efficiently extracted from AEFA, which was mainly composed of NaCaHSiO4.

Decomposition of Bayer process organics: Phenolates, polyalcohols, and additional carboxylates [PDF]
The degradation of nineteen low-molecular-weight phenolates, polyalcohols and selected aliphatic and aromatic carboxylates of relevance to the Bayer process has been studied in 6 mol kg-1 NaOH(aq) at 90 °C for up to 36 days, and (for some species) at 180

An electrochemical investigation of the formation of CoSx and its effect on the anodic dissolution of iron in ammoniacal-carbonate solutions [PDF]
It has been found that the co-presence of cobalt (II) and thiosulphate ions in ammoniacal-carbonate solutions promotes the passivation of iron, under conditions in which it would otherwise continue to dissolve anodically. Electrochemical experiments have
