The present invention provides a method and an apparatus for melting collected printing plates, and a method for recycling collected printing plates that can reduce oxidation losses even when collected printing plates are directly melted together with new metal, and therefore it is possible to obtain a melting yield ratio as high as the melting yield ratio obtained when the collected printing plates are melted in a secondary metal state. New metal 37 is melted in a first melting furnace 12 so as to form molten metal 37A, and the molten metal 37A is sent to a second melting furnace 13. In addition, a vortex 39 that sinks down into the molten metal 37A of the second melting furnace 13 is formed, and collected printing plates 35 are fed into the vortex 39. |
