Silver mining - Wikipedia
OverviewSilver sourcesHistorySee alsoSilver-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.
