Yes. They do.******Contrablue Adds:Unfortunately, this is often incorrect. Many metals are found in chemically "bound" form in their ores -- that is, they are in the form of salts or other compounds rather than the shiny metal. For example, copper is often found in the form of copper carbonate, which is a beautiful green mineral (pure specimens are called "malachite"). But malachite doesn't have a shiny luster because the copper is chemically bonded to oxygen and carbon!The only metals likely to be found "native" or in the uncombined, shiny state, are noble metals such as gold or platinum.The answer is True
Metallic luster is the shiny, reflective appearance exhibited by metals and some minerals. It is typically characterized by a high degree of reflectivity and brightness, similar to the sheen of polished metal surfaces. Minerals with metallic luster often have a metallic appearance due to the presence of metallic elements in their chemical composition.
Adamantine luster is a term used to describe a shiny, brilliant, and reflective luster on minerals or gemstones. It is often associated with diamond-like or metallic sheen, indicating a high level of light reflection and clarity in the material.
Minerals such as galena, pyrite, and halite can have non-metallic luster and exhibit crystal faces that resemble small cubes. These minerals can often form in cubic or octahedral crystal shapes due to their internal atomic arrangement.
Nonmetallic luster refers to a dull or earthy appearance of a mineral or material that lacks the shiny or reflective properties of metallic luster. Nonmetallic luster can be described as having a matte, powdery, or waxy finish, often seen in minerals like talc or graphite.

Yes they doAnswer:Some do and some don't - iron pyrites, gold, silver, lead ores - may have a luster. Others like bauxite (aluminum ore), pitchblende (uranium), iron ore are not lusterous.
In chemistry, luster refers to the way a substance reflects light. Substances with high luster appear shiny and reflective, while substances with low luster appear dull. Luster is often a characteristic used to describe the physical appearance of metals and minerals.

Sulfide minerals are a class of minerals characterized by the presence of sulfur anions combined with metals. They typically have a metallic luster and are often opaque, displaying a range of colors depending on their composition. Common examples include pyrite (fool's gold), chalcopyrite, and sphalerite, which are important sources of metals such as copper, zinc, and lead. These minerals often form in igneous or sedimentary environments and can contribute to economic mineral deposits.

Yes, it is true that many metals, including copper, lead, and zinc, are extracted from ores containing sulfide minerals. These sulfide minerals are often rich in the desired metals and undergo processes such as roasting and smelting to extract the metals. The presence of sulfur can complicate processing, but it also allows for efficient metal recovery when managed correctly.
A mineral containing two or more metals is known as a polymetallic mineral. These minerals can be important sources of multiple metals, such as copper, lead, zinc, and silver, often found in ores like galena (lead sulfide) or sphalerite (zinc sulfide). Polymetallic deposits are valuable for mining as they allow for the extraction of several metals simultaneously, improving economic efficiency.
Adamantine luster is a term used to describe a shiny, brilliant, and reflective luster on minerals or gemstones. It is often associated with diamond-like or metallic sheen, indicating a high level of light reflection and clarity in the material.
The type of luster that gives a mineral the appearance of metal is known as "metallic luster." Minerals with metallic luster reflect light in a way that resembles polished metal, often appearing shiny or reflective. This characteristic is typically seen in minerals like pyrite or galena. In contrast, non-metallic luster includes a range of appearances such as glassy, pearly, or dull.
