According to the copper deportment in the ore; 63.1% of the copper reported as chrysocolla, 22.2% as chalcopyrite, 1.5% as cuprite and 2.9% as malachite/azurite. The focus of the study was therefore on chalcopyrite and chrysocolla because they were the two most abundant copper minerals.
The metals in ore can occur in many different minerals (compounds) in the rock. As an example, copper occurs in more than 50 minerals with varying percentages of copper in the chemical formulas of those minerals. The richest grade of copper ore is native copper, which is pure copper (100%). Many metallic ores occur as sulfide minerals.
Cuprite is a copper oxide, Cu 2 O, and an important ore of copper found in weathered zones of copper ore bodies. (more below) Cuprite is the compound cuprous oxide, with the copper in a monovalent state. Identifying the manganese oxide minerals is a crapshoot without expensive lab equipment,

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.
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin.
ore flux \ m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
As is typical of the copper sulfate minerals, the outer surface has weathered to a lighter blue the larger image (bottom row, middle) shows the true rich blue color. Boothite's a member of the melanterite group. Thanks to Mike Keim at Marin Minerals for the specimen and the image
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).
Copper Ores. This is a large cabinet specimen of mixed copper ores from Morenci, Arizona the large photo shows that there's azurite, malachite, chalcotrichite, crysocolla, turquoise, and probably a lot more minerals here. This one's really fun to look at under a microscope
The first data column contains the total number of minerals listed with Copper and the element listed for that row. The second data column lists this number as a percentage of all minerals listed with Copper. The final data column compares this percentage against the percentage of all minerals that contain the element listed in each row.
This ore from Nevada features the green copper carbonate Malachite. The rich copper minerals boost the copper content of this bonanza grade ore. Azurite The blue carbonate. It has a deep azure blue color, whence the name. The two basic carbonates of copper, malachite and azurite, are common copper ores of secondary origin.
Rio Tinto is engaged in the exploration and production of aluminium, copper, diamonds, gold, industrial minerals, iron ore, thermal and metallurgical coal and uranium. Image 169;2018 Rio Tinto. Headquartered in Melbourne, BHP operates four processing hubs and five mines in Western Australia.
Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of acid. With the availability of real time technology that can reliably measure differences between oxide and sulphide minerals, it is now possible to control a mixed copper ore
In the early 1900s, 30% pure ore (600 pounds of copper per ton) was the average copper content. By the 1930s, ore purity (concentration) had fallen to approximately 4%. Newer mining technologies were developed to process ore with low mineral content, and today it is common to mine ore with a purity of just .35%only 7 pounds of metal per ton

Copper is there in the Earth's outer layer with a concentration of nearly 50 parts per million (ppm), wherein it occurs as native copper ore or in minerals like Copper Sulfides like, Chalcocite and Chalcopyrite, and as copper carbonates like Azurite and Malachite, and also as a copper oxide mineral like Cuprite.
Chalcocite, copper(I) sulfide (Cu2S), is an important copper ore mineral. It is opaque and dark gray to black with a metallic. Chrysocolla (hydrated copper silicate) is a mineral and a minor ore of copper, Southern Arizona
Following is a list of minerals that serve as copper ores in the copper mining process
The froth is skimmed off the surface and the enriched ore (mainly the copper mineral) is taken away for roasting. The mixture of water, foaming agent and paraffin is recycled. After this stage the enriched ore now contains about 25% copper by mass and is called copper concentrate.
Mining for ore has come a long way in the last century. The above images, taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer ( ASTER ) aboard NASAs Terra satellite, show copper mines in Iran. The bright colors correspond to different rock types known as alteration minerals.
Challenges in Ore Characterization. The overall grade of many common ore types is gradually declining. For example, copper ore bodies at Cu grades gt;5% with bornite as the primary copper mineral species are no longer the rule but the exception.
Associated with various copper minerals, most commonly with the oxidized ores, cuprite, malachite and azurite. Most of the copper of commerce is obtained from one or the other of its sulfides. Some, however, is found as the native metal. Copper, often contains small amounts of
