Galena - Wikipedia

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