Sulfide minerals often form in common associations. Pyrite, sphalerite, and pyrrhotite are frequently found together, as are chalcopyrite, pyrite, and bornite or pyrrhotite. In some carbonate-hosted deposits, sphalerite and galena occur together. We can depict sulfide associations using triangular composition diagrams.

Conclusion. Galena that occurs naturally is not magnetic because it lacks unpaired electrons. It can, however, be slightly attracted to a magnet if it contains traces of metals or minerals with magnetic properties. Galena is a diamagnetic material. Hence, temperature has no impact on it.
Cerussite (PbCO3): Cerussite is a lead carbonate mineral that forms in the oxidized zone of lead ore deposits. It is typically found as prismatic crystals or granular masses and can be colorless, white, or gray in color. Cerussite is less common than galena but can be an important secondary lead mineral in some deposits.

The lead sulphide mineral galena, also called lead glance, whilst an important ore of both lead and silver, is also a natural semiconductor. That is to say, it has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. In certain circumstances galena will conduct ...
Galena is a dark gray, shiny mineral that feels surprisingly heavy. It occurs in nature, sometimes in small pebbles and sometimes in bigger chunks like the ones at the Wisconsin Historical Museum. Lead deposits like the …
The property that causes the mineral galena to break into tiny cubes is its crystal structure. This is due to the arrangements of particles and the strengths of the attractions between them in a crystal. Specifically, galena forms cubic metallic crystals due to its atomic structure and electron behavior. Explanation:

Galena is the primary host of Tl in all mapped mineral assemblages. Along with Cu, Tl is likely incorporated into galena via the coupled substitution: (Ag,Cu,Tl)++(Bi,Sb)3+ ↔ 2Pb2+.
Galena is a very soft mineral, registering only 2.5 on the Moh's hardness scale. And even worse, galena has perfect cleavage and brittle tenacity. This means that specimens are very easily damaged by just a tiny chip or bruise. When dropped or smashed, galena easily splits into tiny cubes.
