中文摘要：

以便减少氨和增加的蒸发的率在溶液的铜的溶解度， ethylenediamine 被增加进氨铵氯化物系统沥滤包含铜的氧化物矿石。热力学的模型被构造并且孔雀石 Cu2 的溶解度(哦) 在氨铵 chloride-ethylenediamine 的 2CO3 (在) 水系统基于两个团用指数的计算方法被计算平衡和费用平衡。铜的溶解度能被增加，免费的氨集中能被与 ethylenediamine 提交部分氨减少，这被发现。在溶液的更低的免费的氨集中是到氨的更低的蒸发率的一条保证。孔雀石 Cu2 的条件(哦) 变换成绿盐铜矿 Cu 的 2CO3 (哦) 1.5Cl0.5 也被学习。一组实验被设计验证热力学的计算的结果的诚实。热力学的模型是可靠的，它能指导沥滤的过程，这被发现。

英文摘要：

In order to decrease the evaporating rate of ammonia and increase the solubility of copper in the solution,ethylenediamine was added into the ammonia-ammonium chloride system to leach the copper-containing oxide ores.The thermodynamic model was constructed and the solubility of malachite Cu2（OH）2CO3 in the ammonia-ammonium chloride-ethylenediamine（En）-water system was calculated using the exponential computation method based on both mass balance and charge balance.It is found that the solubility of copper can be increased and the free ammonia concentration can be decreased by submitting partial ammonia with ethylenediamine.The lower free ammonia concentration in the solution is a guarantee to the lower evaporating rate of ammonia.The conditions of malachite Cu2（OH）2CO3 converting to atacamite Cu（OH）1.5Cl0.5 were also studied.A group of experiments were designed to validate the veracity of the results of the thermodynamic calculation.It is found that the thermodynamic model is reliable and it can guide the leaching process.
