Live ChatWhile most minerals are compounds of two or more elements, some minerals are made up of a single element. Gold, silver and copper are called native elements and occur in nature in relatively pure form. Most minerals are compounds or mixtures of elements. It is these compounds that make up the chemical formula and structure of minerals.

Quartz (SiO 2) is treated as one of the silicate minerals.Some of them are primary minerals that solidify deep in the Earth in magmas, but the most common oxide minerals form near the surface where oxygen in the air and
Live ChatThe composition of the sulfide minerals can be expressed with the general chemical formula A m S n, in which A is a metal, S is sulfur, and m and n are integers, giving A 2 S, AS, A 3 S 4 and AS 2 stoichiometries. The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures.
Live ChatQuartz is one of the most common of all minerals that make up the continental crust. It is found in igneous, metamorphic, and sedimentary rocks. It is associated with many valuable ore deposits as well. Amethyst is a variety of quartz and owes its purple color to the presence of iron. It is composed of silicone dioxide SiO 2. Rose Quartz is a variety of quartz and owes its pink color to the
Live ChatCopper found in the free metallic state in nature is called quot;native copper.quot; It is found throughout the world as a primary mineral in basaltic lavas. The greatest known deposit of copper is in porphyries formed by volcanic activity in the Chile's Andean Mountains.
Live ChatOxide minerals have oxygen (O 2) as their anion, but they exclude those with oxygen complexes such as carbonate (CO 3 2), sulphate (SO 4 2), and silicate (SiO 4 4).The most important oxides are the iron oxides hematite and magnetite (Fe 2 O 3 and Fe 3 O 4, respectively).Both of these are important ores of iron. Corundum (Al 2 O 3) is an abrasive, but can also be a gemstone in its
Live ChatThese secondary copper minerals may form rich ore in the upper parts of many deposits, and owing to their characteristic green or blue colour, even small amounts are easily seen in the rocks in which they occur. Copper bearing minerals are commonly found in association with minerals which may contain gold, lead, zinc and silver.
Live ChatCopper is a reddish, relatively abundant, easily worked metal with a bright metallic luster. Its chemical symbol is Cu. Copper occurs as a native metal and as compounds (frequently of sulfur) that are easily smelted. It is a good conductor of heat and electricity, and its main uses are in electrical wire, plumbing, roofing, coins, and jewelry.

Live ChatAug 12, 20130183;32;As the super heated fluids make contact with the seawater, metals that were dissolved from the surrounding basaltic rocks are re deposited on the sea floor. Companies are currently considering undersea mining of this type of deposit in the Red Sea. Minerals associated with mid ocean ridges include iron, zinc, copper, lead, gold, and silver.
Live ChatNative copper is an element and a mineral. It is found in the oxidized zones of copper deposits; in hydrothermal veins; in the cavities of basalt that have been in contact with hydrothermal solutions; and as pore fillings and replacements in conglomerates that have been in contact with hydrothermal solutions.
Live ChatPorphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic

Live ChatCopper and Its Modern Applications. Copper is a mineral by definition because it is a native element on Earth. Its applications range from practical/utilitarian to decorative/ornamental. It efficiently conducts electricity, so it is frequently used in wiring. Copper is also made into alloys with other metals. Combined with zinc, it makes brass.

Live ChatJul 14, 20130183;32;Copper minerals are found in many different ore deposit types and settings, including porphyry, iron oxide copper gold (IOCG), volcanogenic massive sulphide (VMS), strataform and strata bound deposits. Copper porphyry deposits are by far the most common copper ore type, however they tend to be of relatively low grade.
Live ChatCommonly, copper is either formed within sedimentary rocks, or associated with igneous rocks. The worlds major copper deposits are formed within the granitic porphyry copper style. Copper is enriched by processes during crystallisation of the granite and forms as chalcopyritea sulfide mineral, which is carried up with the granite.
