Adsorption of modified dextrins on molybdenite: AFM imaging, contact angle, and flotation studies

► Dextrins adsorbing on molybdenite. ► Adsorption characterised by isotherms and AFM imaging. ► Effect of polymers on wettability determined with contact angle measurements and bubble-surface collisions. ► Flotation of molybdenite correlates with polymer morphology, and subsequent effect of polymer on thin film rupture time.
