From Ore to Finished Product - Copper

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

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 Triton-X 100/cyclohexane water-in-oil microemulsions. The presence of an exceptionally sharp and blue-shifted peak at 475 ± 2 nm in the UV−vis spectrum reveals the formation of quasi-monodispersed, size-quantized particles.

How can I calculate the empirical formula of copper sulfide?

In order to determine the empirical formula for copper sulfide (or for any compound, for that matter) you need to have some information about either the mass of one reactant and the mass of the product, or about the percent composition of the copper sulfide. For the first case, let's assume you are doing a lab experiment in which you heat a mixture of copper and sulfur in order to produce a ...

DIGENITE (Copper Sulfide)

The reasons for this lack of appreciation for digenite could be due to the fact that it does not generally form good crystals, lacks brilliant colors and is easily confused with other copper sulfides. But as is the case for any mineral that rarely forms good crystals, the specimens that do show good crystal habit are in exceptional demand.

Copper Sulfide (CuS) Semiconductors - azom.com

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.
