Abstract (en)
[origin: US4714544A] Process for the selective separation of kaolinite and feldspar by flotation in aqueous pulp, wherein flotation is carried out at the pH-value of the pulp which is naturally obtained during suspension of the mixture of minerals in water using water-soluble salts with trivalent metal ions as activators and depressors, in the presence of cationic and/or anionic surfactants as collectors, and optionally in the presence of other standard flotation aids.
