Galena is the main ore of lead, used since ancient of its somewhat low melting point, it was easy to liberate by typically forms in lowtemperature sedimentary deposits. In some deposits the galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in these deposits significant amounts of silver occur as included silver sulfide ...
