摘 要:
At the total chamber pressure of 1.01 × 101 Pa, Hg, Cd and Zn were distilled at 773 - 973 K from spent zinc-manganese batteries, Pb was volatilized at 1 173 - 1 273 K while Mn, Cu, Fe and C were remained in the residual. MnO2 and ZnO were reduced by carbon in spent dry-batteries at 773 - 1 273 K. Pure metals including Zn, Cd,Hg and Pb were recovered respectively from their mixed vapor by fractional condensation.
