Mica and heavy minerals containing iron oxides and titanium oxides such as rutile and sphene are floated using cationic and anionic collectors, respectively. In this study, the separation of colored impurities including mica and heavy minerals from albite ore obtained from Aydin region in Turkey was investigated by multi-stage flotation. The effects of the new cationic and various anionic collectors and its dosages in acidic or natural circuits were investigated to upgrade the albite ore. In mica minerals flotation stage, the results obtained from this study showed that the stearylamine collector (Flotigam-S) gave the best performance and an albite concentrate with 7.58% Na2O grade was produced with 81.40% Na2O recovery at 400 g/Mg Flotigam-S in acidic condition (pH 3). Additionally, in heavy minerals flotation stage, the use of Na-Oleat in natural circuit (pH 6) was the most effective for the removal of iron and titanium oxides and an albite concentrate with 0.042% Fe2O3 and, 0.061% TiO2 grades was produced with 91.89% Fe2O3 and, 88.56 %TiO2 recoveries, respectively, with the use of 900 g/Mg Na-Oleat. Under the optimum conditions, the results obtained from this study showed that the colored impurities containing mica minerals, iron oxides and particularly sphene as well as rutile were could be effectively removed from the albite ore in the presence of Flotigam-S and Na-Oleat collectors by multi-stage flotation.
