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.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Ammonia and ammonium salts have been recognized as effective leaching agents in hydrometallurgical processes due to low toxicity and cost, easy recovery and high selective recovery of metals.

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...

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 [48]. Pyrometallurgical copper production Figure 3: Typical flow sheet for pyrometallurgical copper production from ore concentrates
A hydrometallurgical process is provided for leaching nickeliferous laterite ores at temperatures below the boiling point of the pulp and at atmospheric pressure. The high iron fraction of the laterite, referred to as limonite, is first contacted with concentrated sulfuric acid to partially or completely dissolve the iron and nickel into solution.
Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore as compared to pyrometallurgy.

Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

leach flow sheet concepts were considered in order to identify the lower capital and operating cost option without negatively impacting precious metals recovery. Pressure oxidation test work was conducted in North America and in Australia on concentrates containing 2.8 – 3.8 g/t gold, 100 – 117 g/t silver, 24 – 26% iron and 27 – 29% sulfur.
Bacterial leaching, combined with SX/EW, offers a method of exploiting small ore bodies with a minimum of capital investment. Most commercial operations leaching copper from ore dumps are located in the Southern Hemisphere in Australia, Chile, Myanmar and Peru.

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 …
Vanadium processing, preparation of the metal for use in various products. Since the early 1900s, vanadium has been used as an alloying element for steels and iron. In 1905 Antenor Riza Patron discovered a large asphaltite deposit containing rich vanadium ores in Mina Ragra, Peru. Two years later ...
ing down through the suIfide ore bodies. When the Moors conquered this part of Spain during the Middle Ages, the oxide ores had largely been exhausted. Learning from the Roman experience with seepage, the Moors developed open pit min-ing, heap leaching, and iron precipitation tech-niques that continued to be used at Rio Tinto into the 20th century.
