RECOVERY METHOD OF VALUABLENESS METALS

摘要

PURPOSE: A recovery method of valuable metals is provided to recover a solid valuable metal concentrated by an environment-friendly and harmless manner using the surface modified biomass, the activated carbon and the carbon nano-tube. CONSTITUTION: A recovery method of valuable metals is as follows. One or more of the surface modified biomass, the activated carbon and the carbon nano-tube are added to valuable-metals containing solution and the valuable metals are adsorbed. The adsorbing material into which the valuable metals are adsorbed, is made into ash. The ash and the valuable metals are heated over a boiling point of the valuable metals and the valuable metals are separated from the ash.
