The Romans were fortunate that the oxide ore was closer to the surface, and that there was a great deal of it. Sulphite Minerals. The Romans did find a way to use the sulfide ores, although the process was very slow and probably produced little copper. They collected water that seeped through the mines. Copper dyed the water blue.

Though they didn't find copper, they got even luckier and discovered gold. In 1901 it boasted a population of 301 people. Even though it was so close to Jerome, it boasted its own post office from 1908 to 1922. But, for Haynes, like Jerome and other area mines, the ore wouldn't last forever.
· Most copper occurs in ores and must be smelted, or extracted from its ore, for purity before it can be used. But natural chemical reactions can sometimes release native copper.
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 .

· Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
· The Iron Age was a turning point in the history of the Land of Israel. Iron tools began to appear around 3,000 years ago, gradually supplanting the softer copper and bronze tools. It was also a time of dramatic political change, as the Hebrew kingdoms, Judah and Israel began to take shape, which may or may not have to do with the advent of iron.
Copper is found in many parts of the world. It usually comes from copper ore, but small amounts are occasionally found ("native copper") in distorted cubic crystal chunks. Keweenaw Peninsula near Lake Superior in Michigan is one of the most likely places to find native copper!! Bingham Canyon mine in Utah. Ore is first mined, then put through a ...
In the language of economic geology, Earth materials are classified as metallic ores, fuel minerals, gemstones, and industrial minerals. Most people know that metallic ores yield shiny, conductive, ductile elements such as copper, iron, or gold. Most understand that energyproducing coals constitute a fuel mineral. Likewise, dazzling rubies and...
· Copper ore can be found close to the earth's surface, as well as in deepsea pockets. It is believed that underwater volcanic activity can produce nodules of copper, magnesium and other metals. Copper is mined in the western part of the United States, Australia, Canada, Mexico, China and a .
· The operation had two components: the mines where ore was extracted from the mountains, and the mill town where the ore was processed. From 1911 to 1938, nearly 200 million worth of copper was processed. At the peak of operation, approximately 300 people worked in the mill town and 200300 in the mines.
This included mines where the copper ore did not protrude to the surface – showing evidence of the advanced knowledge which allowed the prehistoric miners to identify subterranean ores. It also worked the other way around, for sites that showed evidence of ancient mining, were in modern times considered to be good omens, as they were often the best sites to find copper – lots of copper.

The use of copper in ancient China dates back to about 2000 BC. There are ancient copper mines preserved in the mountain of Ural where ore used to be mined 3500 5000 ago. The glaciers of the AustrianItalian Alps have preserved a skeleton of a man who lived in about 3200 BC. A copper axe made of 99,7% pure metal was found close to him.
The company now employs about 350 people and produces 50,000 tons of coppermolybdenum ore per day. At this writing MRI has over 3,000,000 employee hours without a losttime accident. A century of mining left scars that have become the Nation's largest Superfund site, with .
· Most companies mine copper as a coproduct in conjunction with other metals, such as molybdenum, zinc, nickel or lead, and it is typically found in large sulfide and porphyry deposits. These are some of the top active copper mining operations in Canada: Highland Valley Copper Operations. Loion: 17 kilometres west of Logan Lake,
At first, the cosmelting of ores of copper and tin would have been either accidental or the outcome of early experimentation to find out what kinds of rock were capable of being smelted. The smelting of lead was known by 3500 BC and lead, tin and arsenic all appear as alloying elements in smelted copper .
