Selective extraction and recovery of tin from hazardous zinc …
Zinc-leaching residue (ZLR) with 0.46% Sn and 54% Pb brings potential threats to environment but is worthy to recover valuable metals. Reduction of Sn(IV) to Sn(II) is critical for tin extraction. In this work, selective extraction and recovery of tin from ZLR via oxalic acid/sulfuric acid leaching and hydrolytic precipitation was proposed.
