Electrorefining - an overview | ScienceDirect Topics

The gold slimes recovered from the spent silver anodes are melted into impure gold anodes for further refining into pure gold, while the spent silver anodes (typically 15-20% of the original anode weight) are re-melted into fresh anodes to start the electrorefining process anew.

Case Study of emew Silver Process versus Conventional ...

To extract gold and silver from a copper anode slime with about 15% tin in a plant using the traditional pyrometallurgy-electrorefining technique, the recovery is only 90%. The rest of the gold and silver is lost in the slag which contains mainly SnO2, PbO, and Sb2O3 In the present work, a process is developed to recover the gold and silver further.
