feldspar flotation concentrate


  • Concentration of K-feldspar from a pegmatitic feldspar …

    Bench scale flotation experiments were performed to test the effect of NaCl on the ability to concentrate K-feldspar from a pegmatite ore both at natural and acidic pH. A flowsheet is developed as a guide for commercial utilization. The mechanism of the process is elucidated in the light of earlier fundamental results.
