Solvent extraction process for recovering copper from

The copper-containing solution can contain substances, such as copper or sulfuric acid, which can complicate the recovery of metals from the residue. By way of example, sulfuric acid and/or copper can significantly reduce the recovery of precious metals, such as gold and silver, from the residue, using the conventional cyanidation process.
