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. It is not flammable or combustible. The covalent property of sulfur allows sulfur-sulfur bonds and the incorporation of S 2 pairs in some sulfides such as pyrite. [11][12]. Classes of copper sulfides. Although many textbooks (e.g. Whatever their source, copper sulphides vary widely in composition with 0.5 ≤ Cu / S ≤ 2, including numerous non-stoichiometric compounds. There are several copper ores, but they all fall into two main categories: oxide ores and sulfide ores. [13] This apparent discrepancy with the X-ray photo-electron spectrum data simply highlights the problem that NMR has in assigning oxidation states in a mixed-valence compound. Copper disulfide is a metallic conductor due to the incomplete occupancy of the sulfur p band. While the liquid-like Cu ions play an important role for the low κ L and high ZT values, grain-boundary engineering is needed to further enhance the phonon scattering and the thermal stability of Cu 2- x S. Both Cu2S and the copper-deficient Cu1.97S have very similar but distinguishable electronic and crystal structure. The issue of the valence of copper in sulfides (as well as selenides and tellurides) continues to be revisited in the literature. Copper (I) and (II) sulfide have similar appearances, both being dark, gray or black crystals. Chemical intermediate byproduct of the manufacturing processes. Pyrite is a major source of iron and is one of the most abundant of the sulfur minerals. Sulfide ores contain sulfur. Copper (II) Sulfide. These compounds can be differentiated by their crystalline structure. Some copper sulfides are economically important ores. That is because they have high copper content, and the copper in … [6], The bonding in copper sulfides cannot be correctly described in terms of a simple oxidation state formalism because the Cu-S bonds are somewhat covalent rather than ionic in character, and have a high degree of delocalization resulting in complicated electronic band structures. Journal of Solid State Chemistry Volume 238, 25-40. They have a molecular weight of 159.16 g / mol and 95.611 g / mol and a density of 5.6 g / ml and 4.76 g / ml for copper (I) and (II) sulfide respectively (Nati… Properties of Copper Ores The Problem Minerals from which copper can be extracted to make money are called copper ores.
