Silver-bearing ore typically contains very little silver, with much higher percentages of copper and lead. Specific minerals include argentite (Ag 2 S), chlorargyrite ("horn silver," AgCl), polybasite (Ag, Cu) 16 Sb 2 S 11), and proustite (Ag 3 AsS 3). [2] Silver mainly occurs as a contaminant in chalcopyrite and galena, important ores of ...
Silver occurs in veins filling fracture zones through Paleozoic limestone. Minerals in the silver-ore veins include polybasite, pyrargyrite, proustite, sphalerite, galena, and tennantite.
