Numerous minerals occur associated with sphalerite in veins of zinc ore, one of the commonest of these being galena. The more important of the other associated minerals are calcite , dolomite , siderite , pyrite , chalcopyrite , and barite .
Chalcocite (UK: / ˈ k æ l k ə ˌ s aɪ t /), copper(I) sulfide (Cu 2 S), is an important copper ore mineral. It is opaque and dark-gray to black with a metallic luster.It has a hardness of 2 1 ⁄ 2 - 3 on the Mohs scale.It is a sulfide with an orthorhombic crystal system.. The term chalcocite comes from the alteration of the obsolete name chalcosine, from the Greek khalkos, meaning copper.

Ore Minerals. The copper deposits of the White Pine mine are large stratiform deposits in the Nonesuch shale of upper Precambrian age. The ore is typically finely disseminated barely seen in the shale. Copper concentrations average 1-2% Copper.
Most widespread minerals containing Copper; This list of minerals containing Copper is built from the mindat locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Copper mineral species.

Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal in the world.
Tennantite is a copper arsenic sulfosalt mineral with an ideal formula Cu 12 As 4 S 13.Due to variable substitution of the copper by iron and zinc the formula is Cu 6 [Cu 4 (Fe,Zn) 2]As 4 S 13. It is gray-black, steel-gray, iron-gray or black in color. A closely related mineral, tetrahedrite (Cu 12 Sb 4 S 13) has antimony substituting for arsenic and the two form a solid solution series.

Total resource ore contains 0.003 to 0.009% Mo. The Safford mine includes two copper deposits that have oxide mineralization overlaying primary copper sulfide mineralization. The predominant oxide copper minerals are chrysocolla and copper-bearing iron oxides with the predominant copper sulfide material being chalcopyrite.

Most of the silver produced today is a byproduct of mining copper, lead, and zinc. The silver occurs within the ores of these metals in one of two ways: 1) substituting for one of the metal ions within the ore mineral's atomic structure; or, 2) occurring as an inclusion of native silver or a silver mineral within the ore mineral.

Malachite is a green, very common secondary copper mineral with a widely variable habit. Typically it is found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well.
Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals (such as chalcopyrite or chalcocite) and followed by smelting and electrolytic refining to produce a pure copper cathode. An increasing share of copper is produced from acid leaching ...
Chalcopyrite (/ ˌ k æ l k ə ˈ p aɪ r aɪ t,-k oʊ-/ KAL-ko-PY-ryt) is a copper iron sulfide mineral that crystallizes in the tetragonal system. It has the chemical formula CuFeS 2.It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale.Its streak is diagnostic as green tinged black.

The mineral may be a single chemical element, such as carbon (C) [diamond or graphite], sulphur (S), gold (Au), or copper (Cu). Natural metal alloys with definite compositions may be approved as minerals [e.g. auricupride ( Cu 3 Au )].
Minerals and ores. The content of the individual rare-earth elements varies considerably from mineral to mineral and from deposit to deposit. The minerals and ores are generally classified as “light” or “heavy”; in the former group most of the elements present are the light-atomic-weight elements (i.e., lanthanum, cerium, praseodymium, neodymium, samarium, and europium), whereas most ...

Native copper is an uncombined form of copper that occurs as a natural mineral.Copper is one of the few metallic elements to occur in native form, although it most commonly occurs in oxidized states and mixed with other elements. Native copper was an important ore of copper in historic times and was used by pre-historic peoples.. Native copper occurs rarely as isometric cubic and octahedral ...

Bornite is an ore mineral of copper, and is known for its iridescent tarnish. "Peacock Ore", which is sold to amateur mineral collectors and tourists, is often labeled as a variety of Bornite.However, most Peacock Ore in reality is Chalcopyrite treated with acid, which produces a strongly-colored iridescent tarnish.Bornite is named for Ignatius von Born, an Austrian mineralogist and ...
