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.

Nevada's Silver City was established in 1859 after the ore was identified there. Silver City, New Mexico was so named for silver ore that was discovered in 1870, and peak production lasted from 1873-1893. Silver City, Idaho was named for the same reason in 1864 and prospectors flocked to the region to stake mining claims.
