Chemistry for Kids: Elements - Copper

Silver is the only element with a higher electrical conductivity than copper. It is one of the few metals that is not gray or silver in color. The others are gold (yellow), cesium (yellow), and osmium (blue). The compound copper sulfide is used to kill fungi and algae in rivers and ponds.

1999-09-01  Sulphide and flotation concentrates from 33 porphyry copper deposits have been investigated for platinum-group elements (PGE), Au, Cu and platinum-group minerals (PGM). The major sulphides in the samples studied are chalcopyrite and pyrite. Bornite is less frequent and molybdenite occurs in traces only. PGM (merenskyite, sperrylite and an unidentified Pd-Sb telluride) have been

Copper - Element information, properties and uses ...

Copper is not difficult to extract from it ores, but mineable deposits were relatively rare. Some, such as the copper mine at Falun, Sweden, date from the 1200s, were the source of great wealth. One way to extract the metal was to roast the sulfide ore then leach out the copper sulfate that was formed, with water. This was then trickled over scrap iron on the surface of which the copper ...

Copper: The mineral native Copper information and pictures

Native Copper was the only source of copper until the turn of the century, when extraction methods were improved. The copper ores are far more abundant than Native Copper, and are the main source of copper today. Even though, Native Copper is sometimes mined on its own for the copper content. Copper ranks second as the most-used metal in the world.
