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 of 5 percent q:uartz.

Electrostatic feldspar/quartz separation without hydrofluoric acid .Years ago the electrostatic drum separators are replaced by a freefall separator. The setting and maintenance of the freefall separator is easier and it is cheaper to manufacture. It is somewhat more sensitive to the grain size distribution, compared to the drum separator. Moreover we still need an activation by hydrofluoric.a simple method to separate quartz and feldspar . - GeochronometriaA SIMPLE METHOD TO SEPARATE QUARTZ AND FELDSPAR AND ITS APPLICATION TO TL/OSL. 42. H2FSi6) or/and the density separation. The latter is used when the purpose is to analyse the feldspar fraction, and is a rather skilled and time consuming procedure. The acid etching aims at preferentially dissolving.
