| Abstract: | Thermodynamics and kinetics are studied for producing pure copper powder directly from the scraps of ordinary brass. The theoretical analysis and experimental results show that leaching of Zn, Fe, etc. from the alloy is easy, and the oxidation and reduction of the sponge copper resulted from leaching are fast reactions. Besides, the acid leaclling process is controlled by diffusion in the sponge copper, and the kinetic equation can be expressed as for scrap leaching with CHc1=20.2% Further thermodynahac analysis indicates that this process is also sllitable for scraps of all copper alloys, and particularly suited for industrial brass scraps. |
