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.
