Electrokinetic properties of wavellite and its floatability with cationic and anionic collectors

► Microelectrophoretic technique was used for electrokinetic measurements of wavellite. ► The isoelectric point was achieved at the pH 4.5. ► Wavellite-solution interfacial properties are mainly determined by Al and P species. ► Wavellite's floatability was higher with amines. ► Corn starch was not efficient depressant for wavellite.
