| Research Abstract |
We evaluated whether landfill sites can be exploited as a valuable source of various rare metal. This research consists of two kinds of approach. One is to clarify the contents, the chemical form and the enrichment process of metals and temporal changes of mineral composition in landfills. In conclusion, some valuable metals concentrate and exist as sulfide or sulfate or with their minerals in landfills. Another is to develop a nondestructive three-dimensional prospecting system in order to identify metal enriched zones. IP measurements, which focus on chargeability with wastes, are useful.
These observations indicate that landfill sites may be promising for urban mining as rare metals become scarcer.
