The flotation behavior of feldspars is essentially determined by their surface condition and thus by the extent of hydrolytic decomposition of feldspar surfaces 6. The cationic-type collectors, which are most satisfactory for acidic minerals, were used in the flotation of feldspars in the thirties. In 1982, it was found that C 6-14 primary
