Large reserves of feldspar ores exist in the Aegean region of Turkey. Unlike conventional ores, the main impurity in some of these deposits is titanium. In this study, the results of testwork carried out to determine flotation conditions for efficient separation of titatium bearing minerals from two different feldspar ores from the area are presented. The study …
— However, when Orhan and Bayraktar (2006) separated mica from a feldspar ore by flotation with tallow amine acetate as a collector and then separated iron and titanium oxide minerals using sodium oleate, they found that, in the presence of residual amine, co-adsorption of oleate on the feldspar occurred, resulting in the flotation and loss of ...
— In this work, a new flotation strategy was proposed for the flotation of rutile. In this strategy, rutile was activated by Pb(NO3)2 and then floated with amyl xanthate (AX) as a collector at pH 8. Pb(OH)+ was the dominant lead species in the solution at pH 8 and is believed to be the major species reacting with the rutile surface. Time-of-flight secondary …

— Combination of flotation and magnetic separation methods is widely used for enrichment of feldspar ores by purifying from dark-colored gangue minerals such as iron and titanium. In this study, the removal of dark-colored minerals from feldspar ore (Aydin Cine region of Turkey) was studied using a dry magnetic separator. The effect of several …
The flotation behavior of rutile in the system with sodium oleate as collector was studied through pure mineral test. When the dosage of sodium oleate is 20 mg/L, and pH value of the pulp is set from 6 to 8, the flotation recovery of rutile is over 80%. The highest recovery of rutile is 85.27% when pH value of the pulp is 7.5. Zeta potential and IR spectra results …
