How to recover cobalt from waste liquid |
| abstract |
The present invention relates to a method for recovering cobalt from waste liquid, and more particularly, to cobalt oxalate produced by adding oxalic acid or oxalic acid hydrate into waste liquid to recover and recycle cobalt compounds used as catalysts in the malonic ester production process. The present invention relates to a method for recovering by selectively precipitated from impurities. |
