Galena Galena is the major ore of lead, and has been mined and worked since ancient times, e.g. the Romans used lead for weights, coins, vases, plumbing. Galena, a sulphide mineral, contains up to 86% lead, and may contain up to 1% silver. The large volume of galena that is processed for lead produces enough silver as a by-product to also make galena the leading ore of silver.
