    Lithium and rubidium extraction from zinnwaldite by alkali digestion process: Sintering mechanism and leaching kinetics

  • Original language description

    Lithium and rubidium were extracted from zinnwaldite sintering with CaCO3 powders and water leaching the obtained sinters - the alkali digestion process. The experimental results showed that sintering proceeded in three partly overlapping stages: (1) decomposition of zinnwaldite at temperature up to 800 oC, (2) formation of new phases in the temperature range between 750 and 835 oC, and (3) formation of amorphous glassy phase at temperature above 835 oC. The optimal extraction efficiencies of 84% of lithium and 91% of rubidium were achieved at sintering temperature of 825 oC and leaching temperature of 95 oC.
