| Outline of Final Research Achievements |
Reduction-melting can separate heavy metals and precious metals from slag phase, and this process is useful for metal recovery from end-of-life products. However, less noble metals such as rare earth element and transition metals cannot be separated from the slag phase. For separation of these less noble metals, we focused on enrichment of alkaline metal compounds during the reduction-melting. If the less noble metals transfer to the condensed materials of alkaline metals, they are separated from the slag phase. In this study, multi-component heavy metal silicate glass was heat treated under a reductive atmosphere to mechanistically investigate the behavior of alkaline metal enrichment.
