The waste silver oxide button cells used in electric watches with silver contents of around 30 wt.% has been studied for the recovery of silver metal by different routes, e.g., smelting and electrowinning.
Smelting and electrolytic methods are discussed for silver recovery from this battery waste. Acid leaching of waste batteries and precipitation of silver as silver chloride followed by smelting at 1000 °C yields a silver recovery of about 83%.
It needs to point out that high-purity silver has been recovered from spent silver oxide batteries by using aqueous electrolyte. 34 This study demonstrates the first stage of an alternative possessing the abovementioned advantages of ILs.
The significance of recovering silver from spent silicon solar cells cannot be overstated, particularly in light of the increasing demand for silver and the strict environmental regulations in place (Gervais et al., 2023). Moreover, the retrieval of raw materials is crucial for multiple reasons.
From an economic and productivity perspective in the recovery of silver from solar cells, the chemical leaching presents a viable technique. At present, the predominant method for leaching is the utilization of nitric acid, succeeded by precipitation with either NaCl or NaOH or by electrochemical refining.
This study, in partnership with ORIM s.p.a (a company specializing in metal recovery from solid waste in the Marche, Italy), aims to develop a highly selective process for leaching silver particles and subsequently electrodepositing them through environmentally friendly electrochemical methods.
