PURIFYING METHOD OF ELECTROLYTE WHEN COPPER REFINING |
| 摘要 |
The process comprises precipitation of As, Sb, Fe, Bi, Pb and Ag by cupric oxide. The hydrolytic precipitate is separated by filtration and washing. The cupric oxide is also separated by precipitation with sodium hydroxide in alkaline medium and isolation of the sodium sulphate from the solution is undertaken by cold crystallisation.
