Abstract:

the authors did the systematical researches on the interactions of muscovite and different alkaline agents with various concentrations. Liquid and solid parameters were detected, respectively. Results for muscovite in alkalis show there exist instant dissolution trend and vibrating trend during the process.
Difference in concentration of NaOH causes much more difference in dissolution extent than that of NaCO3 does. Silicon/aluminum ratio in reaction solution is equal to that in primary solid, which indicates consistent dissolution occurs. Temperature rise can enhance the dissolution of muscovite in alkalis.
