Abstract (en)
[origin: WO9221443A1] Minerals can be obtained from non-sulphidic ores by flotation if detergent mixtures are used as the collector and contain (a) salts of sulphonation products of unsaturated fatty acids of the formula (I): R?1CO-OH, in which R?1CO is a straight-chain or branched-chain aliphatic acyl group with 12 to 24 carbon atoms and 1 to 5 double bonds; and (b) salts of sulphonation products of unsaturated fatty acid glycerine esters of the formula (II), in which R?2CO is a straight-chain or branched-chain aliphatic acyl group with 12 to 24 carbon atoms and 1 to 5 double bonds and R?3CO and R?4CO, independently of each other, are a straight-chain or branched-chain aliphatic acyl group with 6 to 24 carbon atoms and 0 or 1 to 5 double bonds; plus, optionally, other anionic and/or non-ionic surface-active agents.
