<p>PROBLEM TO BE SOLVED: To provide an evaluation method for valuable metal-containing waste in which a valuable metal is not lost and in which the content of the valuable metal contained in the valuable metal-containing waste is evaluated precisely and to provide a recovery method for the valuable metal in which a control operation is performed easily. SOLUTION: In the evaluation method for the valuable metal-containing waste, the valuable metal-containing waste is dry-distilled and treated in an internal combustion-type dry distillation and gasification furnace, a carbon component is then burned and ashed, its ashed product is then crushed or smashed so as to be mixed, an analytical sample is sampled from its mixture, and the content of the valuable metal is measured. In the recovery method for the valuable metal from the valuable metal-containing waste, the valuable metal-containing waste is dry-distilled and treated in the internal combustion- type dry-distillation and gasification furnace, the carbon component is then burned and ashed, and a valuable-metal component is recovered from its ashed product.</p> |
