Changes in the surface morphology of magnesia particles due to the leaching using hydrochloric acid
Thorough kinetic analysis of the magnesia leaching based on measuring the changes in lixiviant composition revealed that there are differences between the actual leaching behaviour and predictions obtained using the non-porous shrinking particle model (NSPM). A detailed study of the morphology of th...

| Summary: | Thorough kinetic analysis of the magnesia leaching based on measuring the changes in lixiviant composition revealed that there are differences between the actual leaching behaviour and predictions obtained using the non-porous shrinking particle model (NSPM). A detailed study of the morphology of the solid during the leaching process using SEM showed that observed deviations from the NSPM model depend on the particle size; chemical (mineralogical) composition and the polycrystalline nature of magnesia. |
