补充资料：氨浸出
氨浸出
ammonia leaching
o「、J Inehu氨浸出(ammonia leaehing)J下J含氨的水溶液作为浸出剂的浸出方法。氨是·种配位体，能与某些金属离子形成配合物(络合物)进入溶液。浸出过程一般通入氧作为氧化剂，氧化被浸出固体物料中的有价组分。氨浸出可在常压或加压下进行。含自然铜、氧化铜或碳酸铜的矿石，可在常压下浸出;而含铜、镍、钻、锌等硫化物精矿，则采用加压氧氨浸出，浸出温度通常为358一373K，氧气压力为0.7一1.4MPa。浸出液经蒸馏除去的氨，可用水吸收后循环使用。氨浸出的优点是能处理含铁高和含碱性脉石的矿物原料，设备的防腐问题容易解决。由于氨具有挥发性，氨浸出需要在密闭反应器内进行。
