how separate quartz from feldspar

a simple method to separate quartz and feldspar between quartz and feldspar should result in breaking up feldspar grains into particles of smaller size, while leav-ing quartz unaltered. Therefore, sieving of a mixture of quartz and feldspars after having undergone grinding would result in a higher presence of the feldspar grains in the smaller fraction and of quartz grains in the larger one.
