Abstract
Sano, M., Shibata J. and Nishimura S., 1990. New production method of metallic oxide and metal powders. - Application of solvent extraction technique -. Crystallization-stripping under the pressurized CO2 at various combinations of extractants such as VA10, SNA-180, DP-8R and PC-88A and metals such as Ag, Cu, Co, Ni, Zn and Nd were carried out to expand the applicable extraction systems. The metal loaded in VA10 and SNA-180 can be recovered as metal carbonates. The reaction depends on CO2 pressure, extractant concentration and metal concentration in the organic phase. The crystallized products can be converted to metallic oxide by roasting in air and changed to metal by a thermal decomposition in hydrogen atmosphere.
