1 Introduction Froth flotation is the selected method for the separation of quartz and feldspar In the conventional process, feldspar is floated from quartz by using hydrofluoric acid (HF) as activator for the feldspar and a cationic collector (amine) at pH 2–3 (O’Meara, 1939) (1979) reported that HF creates a large difference in the minerals’ zeta potentials as the zeta .
1127 Feldspar Processing 11271 General1 Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks The two types of feldspar are soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O)
However, a HF-free flotation process using a mixture of the cationic and anionic collectors for the separation of feldspar from sand was described by Katayanagi  and the process was reported to be applied in industrial practice   In an aqueous medium the feldspar surface shows, after a short time, changes which have a neg-
