Synthesis and Characterization of Copper Sulfide ...

Nanoparticles of copper sulfide have been synthesized by reacting a copper ammonia complex with an equimolar thiourea solution in TritonX 100/cyclohexane waterinoil microemulsions. The presence of an exceptionally sharp and blueshifted peak at 475 ± 2 nm in the UV−vis spectrum reveals the formation of quasimonodispersed, sizequantized particles....

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 origin....

CHALCOPYRITE (Copper Iron Sulfide)

Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule....

Copper Zinc Tin Sulphide (CZTS) Solar Cells

Dec 11, 2012· The two main types of thin film solar cells are CdTe, cadmium telluride, and CIGS, copper indium gallium, sulphide. Unfortunately there are drawbacks to both of these technologies. Cadmium is toxic and there are issues around the potential scarcity, and consequent volatility in cost, of both Indium, In, and Tellurium, Te....

Copper Sulfide

Abstract: Copper sulfide (CuS) nanotubes assembled by nanoparticles were successfully synthesized by reaction thiourea with Cu(OH) 2 nanowire precursor which was obtained using CuCl 2 and NaOH as raw materials in the solvent ethylene glycol at 80 °C by a facile microwaveassisted solvothermal method. The forming influencing factors of CuS nanotubes were investigated....

University of Minnesota's Mineral Pages: Chalcopyrite

Chalcopyrite is a striking, bright yellow, metallic mineral that occurs in nearly all sulfide deposits. Initially, it may be easy to confuse chalcopyrite, or copper pyrite (CuFeS 2), with pyrite (FeS 2), but the two can be distinguished by their relative hardness and chalcopyrite's iridescent tarnish. Pyrite is the harder of the two and ......

The Bioleaching of copper sulfide ores in saline media ...

The feasibility of bioleaching two Chilean copper ores under saline conditions was evaluated by batch tests. Total copper content of the ores were % and %, respectively. Lower ore mineralogy was comprised of atacamite, chrysocolla, bornite, chalcopyrite, chalcocite, and minor pyrite, while Zaldivar's included brochantite, chrysocolla, chalcocite, and pyrite....
