METHOD FOR RECOVERING VALUABLENESS METALS FROM WASTE PROTEIN SOLUTION CONTAINING VALUABLENESS METALS

摘要

The present invention selectively removes only protein from a solution containing valuable metal, and the protein to highly efficiently recover valuable metal of high purity. The present invention comprises: a step of injecting the solution to be heated and concentrated; a step of manufacturing a valuable metal oxide; a step of oxidize-washing the valuable metal oxide; and a step of recovering the valuable metal oxide.
