چکیده انگلیسی
Separation and recovery process of zinc from scrap copper-based alloy was carried out under vacuum condition in a sublimation reactor. The factors affecting the evaporation ratio of copper-based alloy and the separation efficiency of zinc, such as heating temperature, residual gas pressure, vacuum evaporation time and the amount of scrap copper-based alloy were separately investigated. The experimental results revealed that zinc was successfully separated from the scrap copper-based alloy, where the evaporation ratio of copper-based alloy reached 18.43%. Namely, 96.09% by weight of zinc could be removed under the condition: residual gas pressure of 50Â Pa, heating temperature of 1323Â K and vacuum evaporation time of 90Â min. If corresponding to the residual gas pressure 500Â Pa, the evaporation ratio reached 18.17%, and 94.73% by weight of zinc could be removed under the following experimental conditions: temperature 1323Â K, vacuum evaporation time 180Â min. Meanwhile, the thermodynamics of vacuum sublimation and refining to recover zinc was analyzed and calculated.
