Galena
Galena is a lead-based mineral that is often used in the production of lead-acid batteries. It is also the state mineral of both Missouri and Wisconsin. Galena is most commonly associated with silver, and it is often mined for its silver content as well as its lead content.
Description[edit | edit source]
Galena is a gray, cubic, brittle mineral that is easily recognized by its high specific gravity. It is a common lead ore, and its high lead content makes it a valuable source of this metal. The mineral is named after the Latin word for lead, galena.
Occurrence[edit | edit source]
Galena is found in hydrothermal veins in limestones, dolomites and other sedimentary rocks, as well as in medium- to high-temperature metamorphic rocks. It is also found in pegmatites and in large clasts in alluvial deposits.
Uses[edit | edit source]
The primary use of galena is in the production of lead-acid batteries. It is also used in the manufacture of ammunition, in the production of lead glass, and as a radiation shielding material.
Health effects[edit | edit source]
Exposure to galena can lead to lead poisoning, which can cause a variety of health problems, including damage to the nervous system and kidneys, and can be fatal in high doses.
