Abstract (en)
[origin: WO8100527A1] Froth flotation of sylvinite and other ores in the presence of amine collector is improved by the addition of an amine oxide promoter represented by (FORMULA) where R<u1>u is a linear or branched, substituted or unsubstituted, saturated or unsaturated monovalent aliphatic, alicyclic, alicyclic-aliphatic, or aliphatic-aromatic group which may contain linkages of ether, amine, or sulfide, and R<u1>u has an effective chain length of about 6 to 22 atoms, and R<u2>u and R<u3>u each, independently, is a C<u1>u-C<u4>u alkyl or alkanol group, or R<u2>uR<u3>u is a heterocyclic residue.
