Amine and diamine compounds and their use for inverse froth flotation of silicate from iron ore
摘要：
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.
