废铁中共存的元素的分离·回收方法
摘要：
本发明提供一种有效率且经济性地将废铁中共存的铜等元素分离·回收的方法，所述方法为：将废铁熔融，使所获得的废铁的熔融物与熔融Ag接触，从而基于废铁的熔融物与熔融Ag之间的分配平衡使废铁中共存的元素转移到熔融Ag中，将该转移到熔融Ag中的元素从熔融Ag氧化去除。优选废铁的熔融物含有C，进一步优选C为饱和溶解。
摘要（英）：

Disclosed is a method for efficiently and economically separating and recovering elements, such as copper, that coexist in scrap iron, wherein scrap iron is melted and the molten product of scrap iron obtained is brought into contact with molten Ag. Thus elements which coexist in the scrap iron move to the molten Ag due to the partition equilibrium between the scrap iron molten product and the molten Ag and are removed by oxidation. It is preferable the scrap iron molten product contains C and more preferable said molten product is saturated with dissolved C.
