examples of copper sulfide minerals
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 structuresSome examples of sulfides include galena ( the principle ore mineral for lead and silver), cinnabar (the main ore mineral for mercury), and chalcopyrite (which provides copper)Sulfide Minerals: Definition, Properties & Examples
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 darkcolored streaks, and an igneous originSecondary copper sulfide enrichment is widely accepted today as resulting from oxidation of copper sulfide minerals, downward migration of soluble copper sulfates, and precipitation as copper sulfide by reaction with primary sulfide minerals Chalcopyrite is replaced preferentially to pyriteOxidation of Copper Sulfides and Secondary Sulfide
Copper Sulfide an overview | ScienceDirect Topics
All copper sulfides require the presence of Fe 3+ and O 2 as oxidizing agents for leaching to occur The copper sulfide is oxidized by Fe 3+The resulting Fe 2+ is reoxidized to Fe 3+ by O 2The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevatedtemperature reaction conditions where the sulfurcontaining product is sulfate, rather than the elementalThe flotation is made selective by using reagents, which make the Cusulfide minerals waterrepellant (hydrophobic) while leaving the other minerals wetted (hydrophilic) Typical Cu sulfide recoveries to concentrate are 85–90% Typical concentrate grades are 30% Cu (higher with chalcocite, bornite, and native copper mineralization)Sulfide Ores an overview | ScienceDirect Topics
Copper Ore Types: Sulfides vs Oxides | An Investor's
Copper sulfide ores are typically the most profitable types of copper ores to mine That is because they have high copper content, and the copper in them can more easily be separated from unwantedThe sulphide minerals are compounds of the metals with sulphur Nearly all these minerals have a metallic luster, ie, the peculiar shining appearance of metals, such as gold, silver, copper, lead, tin, iron, etc They are all heavy minerals and nearly all are of economic importance Iron Pyrites or PyriteList Sulphide Minerals Mineral Processing & Metallurgy

Sulfide mineral Wikipedia
The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anionSome sulfide minerals are economically important as metal oresThe sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts Sulfide minerals are inorganic compoundsMost 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 rockformingminerals so it does not give an undistorted distribution of Copper mineral speciesCopper: The mineralogy of Copper Mines, Minerals and More
