文摘
- •
Au, Ag and Pd can be efficiently leached from decopperized anode slime by S2O32 −.
- •
Sn and Sb in the slime have no obvious harmful effect on precious metals leaching.
- •
Pb in the slime can cause seriously detrimental impact on the leaching.
- •
CH3COOH pretreatment can efficiently remove Pb after carbonate transformation.
