Title:
METHOD FOR SEPARATING AND COLLECTING ELEMENT COEXISTING IN IRON SCRAP
Document Type and Number:
Japanese Patent JP2011006749
Kind Code:
A
Abstract:
To provide a method for effectively and economically separating and collecting elements such as copper which coexists in iron scrap.
This separation and collection method includes: melting the iron scrap; bringing the obtained melt of the iron scrap into contact with molten Ag to migrate the elements coexisting in the iron scrap to the molten Ag, on the basis of distribution equilibrium between the melt of the iron scrap and the molten Ag; and oxidizing the elements which have migrated to the molten Ag and removing the elements from the molten Ag. The melt of the iron scrap preferably contains C, and further preferably the C is dissolved and saturated in the melt.
