What is galena chemical formula?
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide (PbS).
What is the density of galena?
about 7.6 gm/cm3
Galena is a noticeably dense mineral, having a density of about 7.6 gm/cm3. It has a metallic luster. Galena has the same cubic structure as common table salt, NaCl.
How is galena used?
Galena is the most important ore of lead. Silver is often produced as a by-product. Most lead is consumed in making batteries, however, significant amounts are also used to make lead sheets, pipe and shot. It is also used to make low-melting-point alloys.
What is the specific gravity of galena?
Galena (PbS) is lead sulfide, the principal ore of lead. It is steel gray, heavy (specific gravity is 7.4 to 7.6), and opaque and has a bright metallic silver-colored luster, although the shiny surface may be dulled by a coating of lead carbonate.
What is galena called?
Galena, also called lead glance, is the natural mineral form of lead(II) sulfide. It is the most important ore of lead and an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals.
What is the ore of galena?
galena, also called lead glance, a gray lead sulfide (PbS), the chief ore mineral of lead.
Why does galena have a high density?
Because lead is a primary element in galena, the mineral has a high specific gravity (7.4 to 7.6) that is immediately noticed when picking up even small pieces. Galena is soft with a Mohs hardness of 2.5+ and produces a gray to black streak. Crystals are common and they usually are cubes, octahedrons, or modifications.
What is galena ore?
Why is galena so heavy?
Why does galena have a high specific gravity?
Is galena toxic?
Galena has a cubic lattice structure and is also a source of silver. 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.
Is galena a metal?
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….
