Abstract (en)

[origin: EP0219057A2] Alkyl glycosides and/or alkenyl glycosides are used alone or as a mixture with at least one anionic, cationic or ampholytic surfactant as collecting agents in the flotation of non-sulphidic ores. However alkyl monoglycosides and alkenyl monoglycosides or corresponding polyglycosides having 2 to 8 glycoside radicals can be used. The alkyl radicals or alkenyl radicals of these compounds can have straight or branched chains and 2 to 18 carbon atoms and, if desired, contain a hydroxyl group and/or an ether bridge in place of a -CH2- group. <IMAGE>
