Adsorption mechanism of mixed cationic/anionic collectors in feldspar-quartz flotation system
A Vidyadhar,K. Hanumantha Rao +1 more
TL;DR: The adsorption mechanism of mixed cationic alkyl diamine and anionic sulfonate/oleate collectors at acidic pH values was investigated on microcline and quartz minerals through Hallimond flotation, electrokinetic and diffuse reflectance FTIR studies.
Journal ArticleDOI
Mixed collector systems in flotation
TL;DR: The interactions between differently structured surfactant molecules at the solid/liquid and air/liquiid interfaces and their effectiveness for efficient flotation were recognized during the 1950's.
