Is Galena hard to find?
Is Galena hard to find?
Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world’s primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and metamorphic rocks in medium- to low-temperature hydrothermal veins. Galena is very easy to identify.
What does Galena smell like?
Gives off a rotten-egg smell in HCl, very high SG, very metallic lustre. Associations: Very common in hydrothermal sulfide deposits.
Why is Galena dangerous?
Galena is a lead sulphide mineral that is one of the primary ores of lead found around the world. The lead in Galena is toxic if inhaled or ingested from dust particles, but the mineral or rock containing the mineral can be handled safely if there is no lead dust present.
How do you mine Galena?
The current mining methods used at the Galena Complex are conventional cut and fill and mechanized cut and fill. Conventional cut and fill is done using the overhand method, utilizing hydraulically placed tailings (“sand fill”) as backfill, typically without the addition of cement.
Is Galena worth anything?
The market value of Galena is dependent on the amount of silver and lead in it. In one ton of Galena the lead is worth 1,720 USD. The silver is worth 7,292 USD.

Does Galena have a rotten egg smell?
Galena, chalcopyrite, sphalerite—sphalerite when rubbed on porcelain creates a yellow streak that smells like rotten eggs (sulfur)
What is the most dangerous rock in the world?
Crocidolite (blue asbestos) Crocidolite, also known as blue asbestos, is considered by many to be the world’s most dangerous mineral. The exposure of this fibrous mineral causes fatal diseases including lung and mesothelial cancer.
Is Galena radioactive?
The high radioactivity of the galena samples is caused by the presence of 210Pb, its decay products (210Bi and 210Po), as well as by secondary radiation, caused by nuclear effects of the interaction of the 210Bi isotope hard b rays with a heavy PbS matrix. 210Pb in galena originates from the uranium-rich coal.

Does Galena occur naturally?
Description: Galena is formed in a wide range of hydrothermal environments. It can be found with sphalerite and chalcopyrite in massive sulfide deposits associated with meta-volcanic rocks, such as the Crandon deposit near Rhinelander. It is a component of some pegmatites and granites, as reported in the Wausau region.
