Flotation Separation Of Feldspar

  • 1212 MINERALOGICAL NOTES

    Flotation separation of feldspars from quartz was first accomplished in 1936 (Ladoo and Meyers, 1951, p. 216) and has been used commercial-ly for many years. For example, the feldspar plant at Kona, North Caro-lina produced from alaskite ore a pottery spar with a maximum amount
