Silver mining Wikipedia
Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag2S), chlorargyrite ("horn silver," AgCl), polybasite (Ag, Cu)16Sb2S11), and proustite (Ag3AsS3). Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of copper and lead, respectively.

Refining (metallurgy) Wikipedia
网页One ancient process for extracting the silver from lead was cupellation. Lead was melted in a bone ash 'test' or 'cupel' and air blown across the surface. This oxidised the lead to litharge, and also oxidised other base metals present, the silver (and gold if present) remaining unoxidised. [1]

How was silver refined in the roman and Iron Age?
网页To extract their precious prize, smelters first reduced the ore to lead containing small quantities of silver. Then, in a process called "cupellation," they oxidized the lead in a shallow porous cup (a "cupel"), by heating it to temperatures above the melting point of silver, 961 degrees.
