Copper is found most often in chalcopyrite, which is a common mineral in sulfide veins. Though iron is often mixed in with the mineral, the copper’s low melting point made it easier to break apart the mineral and heat-separate the copper.

Copper - Most copper ore bodies are mined from minerals created by weathering of the primary copper ore mineral chalcopyrite. Minerals in the enriched zone include chalcocite, bornite, djurleite. Minerals in the oxidized zones include malachite, azurite, chyrsocolla, cuprite, tenorite, native copper and brochantite.

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.
Chalcopyrite is the most common copper ore. It is a mixture of pyrite and copper sulfide. Copper is found in small amounts in living things.
Copper sulfate (CuSO 4.5H 2 0) is a common compound of copper. Copper sulfate is used in copper plating, in fabric printing, and in electric cells.
At Mount Isa, the copper ore bodies are separate from the lead-zinc-silver ore bodies, thus enabling independent production of the two ore types.
Individual copper deposits may contain hundreds of millions of tons of copper-bearing rock and commonly are developed by using open-pit mining methods. Mining operations, which usually follow ore discovery by many years, often last for decades.
The major ores of copper are chalcopyrite,malachite, azurite, and native copper.
Copper metal does occur naturally, but by far the greatest source is in minerals such as chalcopyrite and bornite. Copper is obtained from these ores and minerals by smelting, leaching and electrolysis. The major copper-producing …

The ore bodies are usually irregular and not very large. They are apt to be high in sulphur, from the presence of pyrite and copper pyrites. Garnet, epidote, pyroxene, and apatite are found in the wall rock as well as in the ore.
Collectable Copper Ores and Minerals. This is a selection of the most commonly collected copper ores. Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead and bismuth.
Oct 28, 2009· Best Answer: The most common source of copper is from the mineral chalcopyrite (CuFeS2), which accounts for about 50% of copper production.

15 行· Following is a list of minerals that serve as copper ores in the copper mining process:
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. Sulfide copper ores are the most profitable ores because they have high copper content, and the copper can be more easily separated from the unwanted …
A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of …

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.
Copper(II) compounds of commercial value include cupric oxide (CuO), cupric chloride (CuCl 2), and cupric sulfate (CuSO 4). Cupric oxide is a black powder that occurs as the minerals tenorite and paramelaconite. Large amounts are produced by roasting mixed copper oxide ores in a furnace at a temperature below 1,030 °C (1,900 °F).
Most common isotopes: Cu-63 (69.15 percent natural abundance) and Cu-65 ... Most copper occurs in ores and must be smelted for purity before it can be used.
Where copper and copper alloy scrap is very contaminated and unsuitable for simple remelting, it can be recycled by other means to recover the copper either as the metal or to produce some of the many copper compounds essential for industry and agriculture.
The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different chemistries of the ore. Copper oxides are more abundant near the surface, but are considered low-grade ore, with a lower concentration of copper.
