The initial mining process mirrors that of the granules, involving extraction and primary crushing. Post-crushing, the material undergoes wet grinding using advanced technology. This process involves milling the material with water, which helps in achieving a finer particle size and reduces dust generation. The slurry obtained is then dried and screened to ensure uniform particle size distribution. Wet grinding enhances the brightness and purity of the feldspar powder.
