Mineral Copper Sulphide

Copper sulfide - Wikipedia

Copper sulfides describe a family of chemical compounds and minerals with the formula CuxSy. Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores. Prominent copper sulfide minerals include Cu2S (chalcocite) and CuS (covellite). In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often referred to as "…

Jul 01, 2017· Copper sulfides are a closely related mineral group, and they often occur together. In this bornite specimen are also bits of golden metallic chalcopyrite (CuFeS 2) and areas of dark-gray chalcocite (Cu 2 S). The white matrix is calcite. I'm guessing that the green, mealy-looking mineral is sphalerite (ZnS), but don't quote me.

The Mineral Gallery - Sulfides Class

The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.

sulfide mineral | Definition, Examples, Identification ...

The 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.

Copper Mineral | Uses and Properties

Copper's metallic luster attracted people's attention. Today most copper is produced from sulfide ores. Copper is an excellent conductor of electricity. Most copper mined today is used to conduct electricity - mostly as wiring. It is also an excellent conductor of heat and is used in cooking utensils, heat sinks, and heat exchangers.

Global Marine Mineral Resources - USGS.gov

A wide variety of minerals form through hydrothermal activity, but seafloor massive sulfides are formed from reduced sulfur and may be enriched in copper, zinc, iron, gold, and silver. Hydrothermal vents exist along mid-ocean ridge spreading centers, extensional systems associated with subduction zones, volcanoes, and intraplate hotspots.

ENARGITE (Copper Arsenic Sulfide)

Enargite is related to the rare mineral wurtzite. Wurtzite is a zinc sulfide with a formula of ZnS. In enargite 75% of the zinc atoms are replaced by copper and 25% of the zinc atoms are replaced by arsenic, Cu3AsS4. The similarity is easier to see if wurtzite's formula is rewritten as Zn4S4. The different elements however do not lend ...
