Abstract: Compounds of the formulae: RO-X-NH2 (Ia); RO-X-NH3 + Y- (Ib); RO-X-NH-Z-NH2 (IIa); and RO-X-NH-Z-NH3 + Y- (IIb), in which X is an aliphatic alkylene group containing 2 to 6 carbon atoms; Z is an aliphatic alkylene group containing 2 to 6 carbon atoms; Y- is an anion; and R is an aliphatic iso C13H27- group with average branching degree ranging from 1.5 to 3.5. The compounds are particularly suitable as flotation collectors for enriching an iron mineral from a silicate-containing iron ore.
