摘要：
A metal regeneration method including: a melting furnace cleaning step of melting pure aluminum with an aluminum content of 99.5% by weight or higher in a melting furnace to clean the inside of the melting furnace; and a metal regeneration step of melting waste lithographic printing plates selected from unused lithographic printing plates and used lithographic printing plates, in the melting furnace whose inside has been cleaned by the melting furnace cleaning step, to obtain regenerated metal.
