- Color is lead to silver gray sometimes with a bluish tint.
- Luster is metallic to dull in weathered faces.
- Transparency crystals are opaque.
- Crystal System is isometric; 4/m bar 3 2/m
- Crystal Habits include the cube, octahedron and combinations of the two. Spinel twinning is possible forming flattened crystals. Also massive and granular.
- Cleavage is perfect in four direction forming cubes.
- Fracture is uneven and rarely seen because of the perfect cleavage.
- Hardness is 2.5+
- Specific Gravity is approximately 7.5+ (heavy even for metallic minerals)
- Streak is lead gray
- Associated Minerals are calcite, dolomite, sphalerite, pyrite and other sulfide minerals, also lead oxidation minerals such as cerussite and anglesite.
- Other Characteristics: brighter metallic luster on cleavage surfaces than on crystal faces.
- Notable Occurances include Texas-Oklahoma-Missouri area, USA; Germany, Peru, Mexico, Zambia, and England.
- Best Field Indicators are crystal habit, cleavage and, perhaps most importantly, density.

Do the properties of a mineral depend on the type of mineral?
Yes each different mineral will have a unique set of physical properties.
What is an example of a mineral sulfide?
galena
What type of rock is galena rock?
Galena, lead sulfide, is a mineral, not a rock.
Is galena metamorphic sedimentary or igneous?
Galena is a mineral. not a rock, but is commonly found emplaced in sedimentary rock from hydrothermal deposition in faults and fissures.
What mineral has a hardness of 6 and shows cleavage?

What is galena's fracture?
Galena's fracture is subconchoidal, and its cleavage is cubic. See http://www.minerals.net/mineral/sulfides/galena/galena.htm for a complete chart about galena's properties.
Is Galena a rock or mineral?
Galena is a mineral.
Is galena metallic or nonmetallic?
Galena is metallic.
What physical properties of mineral is?
Physical properties of a mineral are Influenced largely by chemical composition and atomic structure of the mineral.
Is the mineral galena magnetic?
Gallium is malleable. It has a hardness of only 1.5 on Mohs scale.
Is galena a mineral oxide?
No, galena is not a mineral oxide. It is a sulfide mineral composed of lead and sulfur. Oxides are minerals that are composed of oxygen combined with a metal or other element.

Which of these is a mineral sulfidefluoritegypsumiodinegalena?
galena
What Streak color does Galena Mineral have?
Galena mineral typically appears with a streak color that is gray to black.
Can the physical properties of a mineral make it possible to identify the mineral?
yes
What mineral sticks to grease during separation from ore?
Galena, which is a mineral containing lead sulfide, tends to stick to grease during separation from ore due to its natural hydrophobic properties. The grease selectively adheres to the galena particles, allowing them to be separated from the rest of the ore during processing.
