Mineral Species containing Copper (Cu)

Element Properties, Isotopic Compositions for Copper

**Copper (Cu) Element Properties**
Atomic Mass	63.546
Atomic Number	29
Name Origins	Latin, cuprum = "Cyprus."
Year Discovered	Prehistoric
Discovery Credits	Known to ancient civilizations.
Remarks	Reddish metal, malleable and ductile, with high electrical and thermal conductivities. Resistant to air and water but slowly weathers to green patina of basic carbonates. (Historically important alloy, bronze.) Used as wire for conducting electricity; coins; alloys, etc. Diagnostic tests: On charcoal alone, or better with soda (Na₂CO₃), metallic copper can be reduced from most of its compounds. In the case of sulfides the powdered mineral is first roasted before adding the soda. With the borax bead test, it gives a green bead when hot, becoming blue when cold. In solution, copper chloride gives a vivid blue flame test. Roasted ores and non-sulfide copper minerals will give the blue flame by adding HCl to the sample before heating. In solution, the addition of excess amounts of NH₄OH will produce an intense blue color to the sample.
