Copper Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and .
A variety of minerals, both metallic and nonmetallic. What makes an ore different from a rock? An ore is a rock that contains one or more desired metals that can be .
Metallic Minerals. A metallic mineral has a distinctive, shiny, metallic luster. Metallic minerals such as gold and silver are also economic minerals. They are valued as beautiful collectible pieces and also for their potential industrial use. The early history of the state of Colorado parallels the history of metal mining and is directly tied ...
Metallic minerals mostly are found in igneous rocks, on the other hand, nonmetallic minerals mostly are found in sedimentary rocks. Some of the main kinds of metallic minerals include Chalcopyrite (CuFeS2), a copper press sulfide, Gold, Hematite (Fe2O3) which is an iron oxide.
Examples of metallic minerals are iron, aluminum, and copper. Nonmetallic minerals are those which do not yield new products on melting. Examples of nonmetallic minerals are .
Luster: A mineral's luster is the overall sheen of its surface – it may have the sheen of polished metal, or that of an unpolished metal that is pitted by weathering – or it may have the sheen of glass, or look dull or earthy, etc. Luster should not be confused with color: A brassyellow pyrite crystal has a metallic .

Nonmetallic Minerals. Nonmetallic minerals are the type of minerals that consist chemical elements lacking the properties and characteristics of metals. These minerals are mainly consisting of carbon, phosphorus, sulphur, selenium, and iodine. Best and famous examples of nonmetallic minerals are limestone, dolomite, magnesite, phosphorite, talc,...
IV. Hardness. For example, if your fingernail will not scratch (leave a gouge in) the specimen, then the mineral is harder than your fingernail and, therefore, has a hardness greater than In turn, if the mineral can be scratched by a penny, it is softer than the penny and has a hardness less than
A mineral's density is the ratio of its weight relative to the weight of an equal volume of pure water at 4 degree Celcius. False The primary occurrence of the rockforming minerals olivine, pyroxene, and .
Metallic mineral deposits can contain materials such as, lead, zinc, iron, gold, silver, and even indium. Nonmetallic mineral deposits can contain minerals such as silicon, phosphorus, or sulfur.
Vitreous lustre. (The term is derived from the Latin for glass, vitrum .) This type of lustre is one of the most commonly seen, and occurs in transparent or translucent minerals with relatively low refractive indices. Common examples include calcite, quartz, topaz, beryl, tourmaline and fluorite, among others.
Metallic Minerals On an auspicious day, sometime around a million years ago, a member of the Homo habilis species stood erect and walked steadily on his two feet and his two hands became totally free.

Metallic minerals are the minerals that contains metallic elements, whereas nonmetallic minerals are the minerals that doesn't contain metallic elements. Metallic minerals are melted to obtain the new or useful product, on the other hand, nonmetallic minerals do not yield new products upon melting.
Minerals. Specific Gravity (SG) The specific gravity measures the density of the mineral. It is measured in comparison to water where water has a specific gravity of 1. For example, pyrite has a specific gravity of 5 and quartz has a specific gravity of Color Although color is often used to describe a mineral,...
