FLOTATION SEPARATION OF FELDSPAR - KATAYANAGI A,JA

Oct 29, 1974· If the amount of the flotation reagent is increased, the resulting feldspar has a reduced content of Al 2 O 3 and Fe 2 O 3, although the yield of feldspar itself is increased. Therefore, the amount of the flotation reagent should be selected depending upon desired quality of the recovered feldspar and the separation efficiency.
