Lead ore deposits. Galena is often associated with the minerals sphalerite, calcite, and fluorite.. Galena deposits often contain significant amounts (up to one percent) of silver as included silver sulfide mineral phases or as limited solid solution within the galena structure. In addition, zinc, cadmium, antimony, arsenic and bismuth also occur in variable amounts in lead ores.

Galena is a lead sulfide mineral (PbS). It has a metallic luster, silvery-gray color, cubic crystals, cubic cleavage, is moderately soft, and has a very high specific gravity (it's very heavy for its size). Galena is the most important lead ore mineral. It's principally found in hydrothermal vein systems and in Mississippi Valley-type deposits.

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 galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.Galena deposits often also contain significant amounts of silver as included silver
