| titleOfInvention | Recovering method for metal from fluorine compound |
| abstract | PURPOSE: To easily recover Cu, Zn, Cr and Sr with low energy by converting starting material contg. the metals into fluoride and heating and reducing the fluoride in a gaseous flow contg. hydrogen. n CONSTITUTION: Starting material J contg. ≥1 kinds among Cu, Zn, Cr and Sr is fed to a dissolving process E', where an aqueous slon. H contg. fluorine is added to dissolve the material J. Ammonium or a substance contg. ammonium L is added as required. In a filtration separating process D, mother liquor H is separated from a precipitate of ammonium fluorides or acidic ammonium fluorides A of the metals. The precipitate is fed to a heating process B and heated in a gaseous flow G contg. hydrogen to obtain the metals M and a gas K contg. NH 4 F, HF, etc. The produced gas is allowed to be absorbed in water and recycled as a salting-out material. The metallic ions may be extracted with an org. solvent and brought into contact with an aqueous soln. contg. F ion to shift the metallic ions to the aqueous phase, which is then heated in a gaseous flow contg. hydrogen. n COPYRIGHT: (C)1982,JPO&Japio |
