What are the 3 special properties of minerals?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
What are some special properties minerals can have?
The following physical properties of minerals can be easily used to identify a mineral:
- Color.
- Streak.
- Hardness.
- Cleavage or Fracture.
- Crystalline Structure.
- Diaphaneity or Amount of Transparency.
- Tenacity.
- Magnetism.
Does galena have magnetic properties?
The magnetic state of natural galena is due to a sphalerite impurity: The extrema in the temperature magnetization curve are typical of sphalerite.
Is galena rare or common?
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.
What are the 2 properties of minerals?
A mineral species is defined by two distinct properties: (1) its chemical com- position and (2) its crystal structure. Each mineral has a distinct three- dimensional array of its constituent atoms. This regular geometry affects its physical properties such as cleavage and hardness.
Can you get lead poisoning from Galena?
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.

What are the uses of Galena?
Galena is used for multiple things. Galena is mainly used for making lead acid batteries. Some of the other things its used for is making shot (ammunition for shotguns) and lead sheets.
How is Galena valuable?
Galena is a very important mineral because it serves as an ore for most of the world’s lead production. It is also a significant ore of silver. Galena has very few uses beyond its service as an ore, but that should not diminish its importance to society.
What are facts about mineral galena?
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. In sedimentary rocks it occurs as veins,…
What is the luster of Galena?
