Galena Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. It crystallizes in the cubic crystal system often showing octahedral forms. It is often associated with the minerals sphalerite, calcite and fluorite.

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. In some deposits galena contains about 1–2% silver, a byproduct that far outweighs the main lead ore in revenue.

The Mineral galena The Mineral galena. Galena is the most common mineral containing lead, and has been well-known throughout the centuries. It is often well crystallized and forms in many interesting and distinct crystal shapes. Some cubic crystals have their edges cut by the partial octahedral growth, some octahedral crystals have their points flattened by cubic growth, and many crystals are found somewhat in-between cubic and octahedral.

- Galena [PbS] or lead sulphide is the main source of lead [Pb]. It is widespread in the district and is found along with the common vein minerals such as quartz, calcite, barytes and dolomite. Galena has been the most important commercial mineral found in the locality. It was the basis of the Lead Mining industry which was of economic significance, especially during the 18th and 19th Centuries. The Galena crystal group on the left, is an example which was found at Leadhills in the Glengonnar Mine.
