How is Silver Refined?
Silver chloride may then be processed with zinc, sodium hydroxide, and dextrose reduction. Fusion melting is a process that alloys silver and platinum group metals with lead. This process uses zinc which is later removed from the slag. The remaining high-grade silver will still need further refining to meet a target purity of 99.9% fine.
