2001-7-1 · Despite the scarcity of literature on Na-K feldspar separation, the separation of quartz from feldspar has received much attention since 1930. Feldspar has been traditionally separated from quartz using amine type cationic collectors and hydrofluoric acid as activator for feldspar (Shimoizaka et al.,1976; Malghan, 1981; Tang et al., 1993).
