Differbetween
Pyrite and Galena are important sulfide minerals but they are different from each other in various aspects. Pyrite is iron ore while galena is lead ore. This is the main difference between them. ... The color of galena may vary from light gray to dark gray while pyrite is generally brass yellow in color.

How do you identify Galena?
Galena is very easy to identify. Freshly broken pieces exhibit perfect cleavage in three directions that intersect at 90 degrees. It has a distinct silver color and a bright metallic luster. Galena tarnishes to a dull gray.
What do galena and pyrite have in common?
Sphalerite (ZnS), pyrite (FeS2), and galena (PbS) have at least one thing in common: they are all metal sulfides. Many ore minerals (that is, minerals that contain elements of such value that they are mined as "ores" to obtain those elements) are sulfides. ... Sphalerite is mined for zinc, and galena is mined for lead.
Is Galena dangerous to handle?
Galena - PbS
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.
What is the use of Galena?
Galena is the primary ore of lead, and is often mined for its silver content, such as at the Galena Mine in northern Idaho. It can be used as a source of lead in ceramic glaze.
Is Galena worth money?
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.
Where is Galena most commonly found?
Galena is found in cavities and brecciated (fractured) zones in limestone and chert, as in the extensive Mississippi River valley deposits, where 90 percent of the U.S. production of lead is mined. The mineral has occasionally been observed as a replacement of organic matter and sometimes occurs in coal beds.
What special property does pyrite have?
| Physical Properties of Pyrite | |
|---|---|
| Chemical Classification | Sulfide |
| Mohs Hardness | 6 to 6.5 |
| Specific Gravity | 4.9 to 5.2 |
| Diagnostic Properties | Color, hardness, brittle, greenish black streak, specific gravity |
Does Galena have any special properties?
Description and Identifying Characteristics
Its perfect cubic cleavage, metallic luster, lead-gray color, and relative softness readily distinguish galena from most other metallic minerals. Perhaps its most distinctive feature though, is its very high density (high specific gravity).
Is all pyrite magnetic?
Pyrite is not magnetic. Some related minerals are, but only weakly, not as strong as iron, so the test will likely fail anyway.
What crystals are dangerous?
Stone cold – the 11 most dangerous minerals
- Crocidolite (blue asbestos) Crocidolite, also known as blue asbestos, is considered by many to be the world's most dangerous mineral. ...
- Erionite. ...
- K-Feldspar. ...
- Quartz. ...
- Pyrite.
How is pyrite dangerous?
When coal burns, pyrite is oxidized thus releasing arsenic. For instance, the occupational lung disease of miners is caused by pyrite. Pyrite is a main source of acid gases in the atmosphere. Therefore, I consider pyrite the most dangerous mineral for human health, - said the scientist.
How is Galena formed in nature?
Cordua.) 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.
