How Is Galena Mined

galena - university of auckland,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..lead ore mining equipment-galena ore processing,lead ore mining equipment-galena ore processing & upgrading machine. the lead ore can be upgraded by different methods and lead beneficiation equipments according to different types of ores, but generally speaking, lead gravity separation, lead floatation separation, or combination of gravity separation and floatation separation can be involved in the lead processing line to get high grade.
