- •
E-pH diagrams of As/Sn/Pb/Cu-H2O systems were established.
- •
Tin and arsenic were selectively extracted from tin anode slime.
- •
92.16% Sn and 96.49% As were extracted by alkaline pressure oxidative leaching.
- •
About 95% As was removed from the leachate as sodium arsenate hydrate.
- •
The final solution can be used to produce sodium stannate.
