Study on Technology of Extracting Potassium with Alkaline Hydrothermal Method

Abstract:

In this thesis, potassium feldspar - NaOH reaction system under hydrothermal conditions was established. The aims of this research were to discuss comprehensively the factors affecting potassium dissolution rate of the system. The experimental result indicated: effect on the extracting rate of potassium, NaOH concentration > the reaction temperature > reaction time; The rate of extracting potassium can be up to 70% under the optimal conditions; XRD phase analysis of ore and slag filtering showed that NaOH additive destroyed the crystal structure of potassium feldspar, and formed a new phase.
