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 2.The Fe(II)/Fe(III) redox couple acts in a catalytic manner in these reactions (shown for elevated-temperature reaction conditions where the sulfur-containing product is sulfate, rather than the elemental ...
Copper sulfide occurs in nature as the blue mineral covellite, that turns black in air. It is used in antifouling paints and in textile dying with aniline black. Copper sulfide was probably used as a black pigment in antiquity (Orna et al 1980). Spots of black copper sulfide can sometimes be seen on corroded bronzes. Synonyms and Related Terms

This method, developed by Lionel Milberger, is a low-cost, accessible way to detect if hydrogen sulfide is present in the air. The elemental copper will react with hydrogen sulfide to produce a purple-black-ish copper sulfide product, visible on the surface of the copper rod.
Copper concentrations were most likely limited by the low solubility of copper. Copper removal may be due to malachite precipitation or adsorption onto silicates or other surfaces. Due to its low sulfide solubility log ksp = -36.1 (11) it also has a high tendency to participate in exchange reactions with metals of greater sulfide solubility.

Copper sulfides can be classified into three groups: Monosulfides, 1.6 ≤ Cu/S ≤ 2: their crystal structures consist of isolated sulfide anions that are closely related to either hcp or fcc lattices, without any direct S-S bonds. The copper ions are distributed in a complicated manner over interstitial sites with both trigonal as well as distorted tetrahedral coordination and are rather mobile.
The common route for turning copper sulfide ores into metal is high temperature oxidation of sulfides to produce an impure liquid copper. This is cast into slab-like anodes. Principal impurities are iron and precious metals (gold and silver). The anodes are electrolytically refined in cells sketched in Fig. 8.There is a resemblance to the cell of Fig. 7.
Copper is not difficult to extract from it ores, but mineable deposits were relatively rare. Some, such as the copper mine at Falun, Sweden, date from the 1200s, were the source of great wealth. One way to extract the metal was to roast the sulfide ore then leach out the copper …

Sulfide Ores. Sulphide ores were mostly created by (i) the intrusion of molten magma from the mantle into the crust of the earth and (ii) the formation of localized metal-rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation.
The number of electrons in each of copper's shells is 2, 8, 18, 1 and its electron configuration is [Ar] 3d 10 4s 1. The copper atom has a radius of 128 pm and a Van der Waals radius of 186 pm. Copper was first discovered by Early Man prior to 9000 BC. In its elemental form, copper has a red-orange metallic luster appearance.
