As the rare metals have many advantages in high technology fields, its stable supply for current demands are highly important problems of resources for industrialized country like Japan. Rare metals are condensed as waste or scrap during imports of these metals from aboard. Since these rare metal scraps become urban mineral, development of urban mine will be effective for the stable supply of rare metals.
The present situation of resources such as demand, supply, material production and recycle technology are described for rare metals of titanium, zirconium, vanadium, niobium, tantalum, chromium, molybdenum, tungusten, rare earths, nickel, cobalt, garium, indium and germanium.
