Galena
A variety of Galena Group
What is Galena?
Galena is a distinctive, lead-containing mineral with a strong metallic luster. It is often found alongside silver, and has been mined for centuries in pursuit of those two elements. A powdered form of the mineral was worn around the eyes in ancient Egypt – both cosmetic and practical, it helped reduce the glare of the desert sun. Specimens of galena forming large cubic or octahedral crystals are prized by rock hounds and collectors.
Uses & Applications
Galena can be smelted in order to obtain lead and silver. While it has few uses outside of being a common ore mineral, the lead obtained from this mineral is commonly used in batteries, particularly auto-batteries used in vehicles which can last for several years.
Healing Properties
Galena is believed to be a grounding stone, which removes emotional blocks and helps to restore a person's motivation and drive. It is believed to enhance kindness and sensuality and is recommended to be worn, kept in your pocket, or placed in your home to restore energy in all aspects of your life.

Geochemistry
Within the weathering or oxidation zone galena alters to anglesite (lead sulfate) or cerussite (lead carbonate). Galena exposed to acid mine drainage can be oxidized to anglesite by naturally occurring bacteria and archaea, in a process similar to bioleaching.

Key Characteristics
Formation of Galena
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.
Composition of Galena
Galena belongs to the octahedral sulfide group of minerals that have metal ions in octahedral positions, such as the iron sulfide pyrrhotite and the nickel arsenide niccolite. The galena group is named after its most common member, with other isometric members that include manganese bearing alabandite and niningerite. Divalent lead (Pb) cations and sulfur (S) anions form a close-packed cubic unit cell much like the mineral halite of the halide mineral group. Zinc, cadmium, iron, copper, antimony, arsenic, bismuth and selenium also occur in variable amounts in galena. Selenium substitutes for sulfur in the structure constituting a solid solution series. The lead telluride mineral altaite has the same crystal structure as galena.
