METHOD OF RECOVERING INDIUM FROM ZINC SULFATE SOLUTIONS |
| 摘要 |
<p>hydrometallurgy. SUBSTANCE: indium is recovered from zinc sulfate solutions by extraction with solutions of di(2- ethylhexyl)phosphoric acid in hydrocarbon diluents or without them and in presence of monocarboxylic acids in organic phase. Indium is then reextracted from organic phase by sulfuric acid solutions containing chloride ions. EFFECT: enhanced process efficiency due to decreased dependence on extractant composition, reduced fire risk, and simplified control. 3 tbl, 3 ex</p> |
