Abstract
A collecting agent and method for the recovery of valuable minerals in the froth flotation beneficiation of non-sulfidic ores is provided. The collecting agent is selected from alkyl glycosides, alkenyl glycosides and mixtures thereof. Preferably, the collecting agent is a combination of an alkyl glycoside, an alkenyl glycoside and mixtures thereof with a non-thio ionizable surfactant collector. Glycosides containing from about 2 to 8 glycoside residues may be used. The alkyl and alkenyl components of these glycosides may be linear or branched, may contain from about 2 to 18 carbon atoms and may optionally contain a hydroxyl group or an ether linkage.
