Outline of Final Research Achievements |
We found that hydrogen reduction of trace amount of iron or cobalt oxide contained as a solid solution in aluminosilicate was enhanced by adding sodium borate as a flux and that iron or cobalt metal was easily deposited on the surface. Iron with metallic luster was deposited by heating aluminosilicate containing 0.50 wt% of iron as a solid solution in hydrogen at 950°C with a sodium borate (3Na2O・B2O3) flux. Furthermore, it was suggested that cobalt and indium could be also separated by the reduction according to the thermodynamic control. It is expected our findings will lead to the separation of rare metals from industrial wastes and low-temperature refining process of high melting metals.
