The fundamental studies on production of metallic oxide and metal powders with crystallization-stripping using NH4HF4, (NH4) 2S04 and pressurized C02 gas as crystallization-stripping agent in solvent extraction were carried out in order to develop a new production method of fine powders. The reaction significantly relates to the stripability of the extracted metal tons and the solubility of the metal compounds formed in crystallization process. Furthermore, the reaction depends on the various factors, such as extractant concentration, metal concentration in the organic phase, the sort of stripping solution and still more CO2 pressure in the pressurized CO2 process. The resultant crystallized products can be converted to fine powders of high-purity metallic oxide and metal in micron order by thermal decomposition in air or hydrogen atmosphere, respectively. |
