摘要：
The invention concerns a process for enriching an iron mineral from a silicate containing iron ore by inverse flotation comprising the addition of a collector or collector composition comprising at least one of the compounds of formulae RC(O)N(Z—O—X-NH2)2 (Ia); RC(O)N(Z-O-X-NH2)2H+ Y− (Ib); 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 a saturated or unsaturated, linear or branched, aliphatic or aromatic moiety having between 7 and 23 carbon atoms. The invention also relates to the novel compounds according to formulae (Ia) and (Ib), compositions comprising said compounds and the use of compounds and formulations as collectors for enriching of iron mineral.
摘要（中）：
本发明涉及通过反浮选从含铁矿石的硅酸盐中富集铁矿物的方法，包括加入收集物或收集器组合物，该组合物包含至少一种式RC（O）N（ZOX-NH 2）2（Ia ）; RC（O）N（Z-O-X-NH 2）2 H + Y-（Ib）; 其中X是含有2至6个碳原子的脂族亚烷基; Z是含有2至6个碳原子的脂族亚烷基; Y-是阴离子; 且R为具有7至23个碳原子的饱和或不饱和的直链或支链的脂族或芳族部分。 本发明还涉及根据式（Ia）和（Ib）的新化合物，包含所述化合物的组合物和使用化合物和制剂作为铁矿物富集的收集剂。
