Copper/Molybdenum Ore. The figure above is a simplified flow sheet showing the basic steps involved in a copper mill producing the byproduct molybdenum. The crushed copper ore (containing, for example, 0.75% Cu and 0.015% Mo) is fed to the grinding circuit where water is added and the ore is ground to the proper size.
What are the different types of copper ore, and how are they processed? Here's a brief primer on the subject for investors.
The copper concentration in copper ore deposits has shown changes throughout history. From 1880 to about 1960 the grade of copper ore showed a steady decrease from about 3% to less than 1%, mainly due to increased efficiency of mining.
Native copper is an element and a mineral. It is found in the oxidized zones of copper deposits; in hydrothermal veins; in the cavities of basalt that have been in contact with hydrothermal solutions; and as pore fillings and replacements in conglomerates that have been in contact with hydrothermal solutions.

Mining copper ore is arguably easier for Alliance players--Elwynn Forest, Westfall, and all of the dwarven countries are rich with copper ore nodes. Loch Modan, Dun Morogh, and to a lesser extent, Elwynn Forest, are the best locations to farm copper ore for Alliance WoW players, however.

Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated .

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).
Though these pieces certainly were the most valuable ore, the best specimens from the area are clusters of well formed copper crystals. Other metallic minerals can be found with the native copper such as silver, domeykite, mohawkite, and chalcocite.
copper produced in the United States originated from flotation (Daniel E. Edelstein, Copper Commodity Specialist, U.S. Geological Survey, written commun., March 20, 2012). Copper sulfide ores must be concentrated before they can be economically transported to a smelter.

There are two main copper ore types of interest, copper oxide ores and copper sulfide ores. Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.

Copper Mining and Processing: Processing of Copper Ores Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.
Azurite is a secondary mineral that usually forms when carbon-dioxide-laden waters descend into the Earth and react with subsurface copper ores. The carbonic acid of these waters dissolves small amounts of copper from the ore.
Bornite is an important copper ore mineral. It ranks up there with many of the other copper ores such as chalcocite, chalcopyrite, covellite, digenite, cuprite and tetrahedrite. As a mineral specimen, bornite is usually lacking. Good crystals are rare and thus bornite is commonly known as simply a massive mineral ore.
Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble metals (not usually forming compounds) such as gold. The ores must be processed to extract the elements of interest from the waste rock and from the ore minerals.
