Copper is not difficult to extract from it ores but mineable deposits were relativelyrare. Some such as the copper mine at Falun Sweden date from the 1200s were thesource of great wealth. One way to extract the metal was to roast the sulfide ore then
Uses of Copper. Native copper was probably one of the early metals worked by ancientpeople. Nuggets of the metal could be found in streams in a few areas and its propertiesallowed it to be easily worked without a required processing step. Today most copper is
Copper is a chemical element with the symbol Cufrom Latin: cuprumand atomic number29. It is a soft malleable and ductile metal with very high thermal and electricalconductivity.A freshly exposed surface of pure copper has a pinkish-orange color.Copper
Copper ore deposits are known in North America South America and Africa. Copper isobtained by smelting leaching and electrolysis of the copper sulfides oxides andcarbonates. Copper is commercially available at a purity of 99.999%. Element
