2019-5-1 · Before the leaching process, the kaolin ore and limestone charge was sintered. The sintering process achieves the dehydroxylation of the kaolinite, which is the main mineralogical phase in the kaolin and activates its transformation to metakaolin. Metakaolin is an amorphous Al Si phase, from which alumina could be easily leached. The annealed sintered material transform into dust that is suitable for …

Ce processus permet aux particules plus fines et plus légères de kaolinite de se déposer dans les eaux calmes des lacs ou des estuaires, produisant ainsi des kaolins exceptionnellement purs (85 à 95 % de kaolinite), pratiquement exempts de particules sablonneuses (Prasad et al., 1991). Par contre, lorsque le dépôt de kaolinite se fait en milieu marin plus perturbé, le kaolin peut contenir une quantité élevé de …
