Hydrometallurgical process for copper-containing materials |
摘要 |
The present invention is directed to a process for recovering copper from a copper-containing material by pressure oxidation followed by solvent extraction and electrowinning. The copper-containing solution formed by pressure oxidation is diluted before solvent extraction and the raffinate solution from solvent extraction is neutralized to reduce the acid levels in the raffinate solution.
