PROBLEM TO BE SOLVED: To provide a method and apparatus for treatment of molten slag, and an inorganic structural material of a matter treated by the apparatus, and preparation of high purity hydrogen and the like. SOLUTION: The method for molten-slag treatment is characterized by that (1) the molten slag is treated with a treating agent containing an alkali and/or alkaline earth ions, or a treating agent containing a supply source of pertinent ions, (2) metal components contained in the molten slag are converted into an inactive compound. There are provided further in this invention an apparatus for the treatment, a method for recyling the molten slag, and products of recycling. The fixed molten slag is chemically inactive, and can be used safely as construction materials, such as cement aggregate, roadbed materials, blocks, etc. COPYRIGHT: (C)2003,JPO
