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 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 - CAMEO

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

Sulfide Oxidation - 911metallurgist.com

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 sulfide - Wikipedia

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.
