In the case of silver sulfide dissolution, the results revealed that the reductive decomposition of silver sulfide is favored at a more cathodic potential than −0.6 V vs SHE with the MEA-Na 2 SO 4-(NH 4) 2 SO 4 system, this cathodic pre-treatment facilitates the accelerated dissolution of silver from Ag 2 S using the same MEA leaching system.
Copper Co-deposition. Looking at the standard potential of Cu (Cu/Cu 2+ = 0.345 V and Cu/Cu + = 0.522 V), it is apparent that during electrorefining of Ag, Cu will mostly dissolve into and enrich in the electrolyte. Partial occurrence of Cu in the anode slime can be detected. This is more or less due to oxidic Cu present in the crude silver …
Due to the increase in electric and electronic equipment (EEEs), high-purity silver continues to be in high demand. For the past 4 years, silver demand has exceeded silver mining production, but the global supply has nearly met the demand each and every year – thanks to silver recovery and silver refining.
