A process for the extraction of copper a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper.
Most nonconventional hydrometallurgical methods of the processing of complex sulfide ores are based on metals extraction from bulk flotation concentrates (2.1 12,111. The recovery of zinc, lead and copper by froth flotation, even as a relatively rich concentrate, presents today a rather routine problem.

Tables 61 and 62 provide capsule summaries of these processes. 1 PyrometaIIurgy IS the extractIon of metaI from ores anD concentrates using chemical reactions at high temperatures. 2 Hydrometallurgy is the recovery of metaIs from ores using waterbased solutions. As early as 6000 B. C., native copper
Solvent extraction is more efficient in the separation of metals than selective precipitation. The objective of this study was to develop a hydrometallurgical process capable of effectively separating aluminum, cobalt, copper, and lithium.
Dr. David Dreisinger and International Curator Resources developed a process for the hydrometallurgical extraction of copper, zinc and cobalt from ores containing manganese dioxide. This was applied at the El Boleo mine (Patent Application WO1998014623A1 ).
The solvent extraction with 40%((p) LIX84 adding 0.1 mol/L TBP in the organic phase and a phase ratio of 11 in 30 min of contact resulted in 81% of copper extraction rate and 85 mg/L of ammonia
An alternative process by using hydrometallurgical leaching followed by electrochemical recovery of copper from the leach solution is also frequently used .

The leaching of this ore requires knowledge of the gangue mineralogy. It is the gangue that is consuming the acid. The bacteria will be on the surface of the copper and extraction can be achieved. The challenge is defining operating parameters that minimize degradation of the gangue to maintain permeability and extract the copper.

Tank Leaching Process. mining hydrometallurgical process for copper extraction offers 606 tank leaching process products.
Minor impurities, including precious metals, settle at the bottom of the cell as anode slimes for further processing. Copper in solution from a hydrometallurgical process is recovered in a similar electrolytic cell using a lead anode.
The use of solvent extraction (SX) in the hydrometallurgical refining of copper is a wellestablished technology, with most hydrometallurgy copper producers including SX as a unit operation in their overall process flow sheets.
Copper extraction techniques Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS 2 ), which accounts for about 50% of copper production. The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal.
