Precipitate Flotation of Aluminum and Copper - Science Alert
Finally, in this precipitate flotation the fundamental process may be the interaction of the HOL surfactant with the colloidal precipitates of aluminum and copper. This process renders the surface hydrophobic and so enables the precipitates to be held at the air-water interface and floated to the surface.
