Copper Brass Bronze. Copper is a reddish-orange metal that is plentiful in nature. Copper ore can be found in many different ore minerals, among them chalcopyrite mineral, chalcocite mineral, covellite mineral, bornite mineral, azurite mineral, dioptase mineral, tennantite mineral, chrysocolla mineral, and.The ore itself averages less than 0.7 copper in US mines. Copper ore normally is crushed, ground, and concentrated, usually by flotation, to produce a beneficiated ore containing about 25 copper. The ore concentrates are reduced to the metallic state, most often by a pyrometallurgical process.After this stage the enriched ore now contains about 25 copper by mass and is called copper concentrate. It is valuable enough to ship to other plants and other countries for processing. For example China, Germany and Japan are major copper producers that use concentrate from around the world.On the pages I have images of native gold and platinum plus a variety of different ores for gold, silver and copper, plus info about these ores and where they are found.

Photo Gayane Mkrtchyan OC Media. For years the copper smelter was the economic heart of Alaverdi, but its operation came at a price, the plant spewed thousands of tonnes of toxic emissions into the air.
