examples of copper sulfide minerals

sulfide mineral Definition, Examples, Identification

Weathering may act to concentrate dispersed sulfides. Sulfide minerals are the source of various precious metals, most notably gold, silver, and platinum. They also are the ore minerals of most metals used by industry, as for example antimony, bismuth, copper, lead, nickel, and zinc.

Oxidation of Copper Sulfides and Secondary Sulfide

Secondary 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 pyrite.

Copper Ore Types: Sulfides versus Oxides Nasdaq

Apr 23, 2011· Sulfide copper ores are the most profitable ores because they have high copper content, and the copper can be more easily separated from the unwanted minerals. It is important to note that sulfide

Mineralogy of Sulfides Elements GeoScienceWorld

Pyrite is the dominant sulfide in porphyry copper deposits, though it is chalcopyrite that is the most important ore mineral, along with bornite and various binary copper sulfides. In the related porphyry molybdenum deposits, it is molybdenite that dominates. The sulfides in such deposits occur as veinlets or disseminated grains in host intrusions.

Sulfides, minerals: physical properties, application

For example, chalcopyrite, cuprite, bornite copper-bearing minerals occurring together. Most often, ore bodies of sulphide deposits have the form of veins. But there are also lenticular, stock, reservoir forms of occurrence. Sulphide application. Sulfide ores are extremely important as a source of rare, noble and non-ferrous metals.

Direct extraction of copper from copper sulfide minerals

Here we provide the first demonstration that electrochemistry in Deep Eutectic Solvents can solubilise and directly recover high purity copper from solution from three copper sulfide minerals: covellite (CuS), chalcocite (Cu 2 S) and chalcopyrite (CuFeS 2). Cyclic voltammetry supported by EXAFS identifies the metal speciation in solution.

Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

ROASTING OF SULFIDE MINERALS

ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other metals such as antimony, bismuth, cadmium, cobalt, mercury, and molybdenum occur as sulfide minerals. Sulfides are not reduced with the most widely used redu-cing agents, carbon and hydrogen, because the free energy change for the

Sulfide mineral Wikipedia

The sulfide minerals are a class of minerals containing sulfide (S 2−) or persulfide (S 2 2−) as the major anion.Some sulfide minerals are economically important as metal ores.The sulfide class also includes the selenides, the tellurides, the arsenides, the antimonides, the bismuthinides, the sulfarsenides and the sulfosalts. Sulfide minerals are inorganic compounds.
