A SIMPLE METHOD TO SEPARATE QUARTZ AND

2008-5-21  Grinding together quartz and feldspar grains in an agate mortar results in crushing the feldspar fraction due to its smaller hardness. Later sieving of the grinded mixture enables simple separation of both fractions. Then it is possible to save the feldspar fraction for later analyses instead of losing it as it occurs when using acid etching. Also,

The friction between quartz and feldspar should result in breaking up feldspar grains into particles of smaller size, while leaving 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.
