其中，对金属Ⅰ的过程为：继续升高非金属母液的温度，使非金属母液的温度大于金属Ⅰ的熔点且小于金属Ⅱ的熔点，待金属Ⅰ通过非金属母液全部变成熔液后，通过熔液出口排至冷却及分离系统中，其中，不相溶的非金属母液及金属熔液在冷却及分离系统中冷却并利用不相熔的特点进行分离，其中，非金属固体从冷却及分离系统的非金属出口排出，金属固体从冷却及分离系统的金属出口排出。

对熔池发生系统进行升温至非金属母材熔点温度以上50℃，使非金属母材形成非金属母液。
非金属固体从冷却及分离系统的非金属出口排出，最终再进入到熔池发生系统回用。
本发明具有以下有益效果：
本发明所述的利用非金属母液回收金属的系统及方法在具体操作时，根据物料中金属组分的物理特性，选择一种非金属母材作为熔池发生系统的母材，确保该非金属母液与金属熔液之间互不相溶，然后对熔池发生系统进行升温，使非金属母材形成非金属母液，根据物料中金属组分的熔点从低至高的顺序依次对各组分金属进行回收，通过非金属母液以物理方法低成本回收物料中各组 分金属物质，并利用非金属母液与金属熔液不相溶的特性在冷却过程中进行固态分离，系统简单、物料适应范围广、不消耗其它物质，能耗低、环保性好，对不同组分金属的回收有特殊意义，为国家绿色发展和全社会资源综合利用提供了重大技术支持。
