    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 ...

  • Mineral processing - Wikipedia

    As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals. It is then concentrated using mineral flotation.
