Antimony recovery from secondary resources containing antimony by vacuum metallurgical process
The recovery of antimony from secondary resources containing antimony (anode slime, slag, waste antimony products) by using vacuum metallurgical process will be investigated. The thermodynamic and kinetic models of vacuum metallurgical process will be set to understand the reaction mechanism. Different factors (temperature, vacuum degree, duration time) during reactions will be optimzed to create an optimal reaction condition. Meanwhile, the separation of antimony from other elements (lead, bismuth, zinc, arsenic) under vacuum condition needs to be investigated to better recover antimony.
